I'm installing a weather station for a local elementary school on my roof that the kids will be able to access over the Internet. Because I'm paying for this out of my pocket my budget is very limited and Eva electrician I talk to wants to charge me an arm and leg.

I would try to mount it on a pole away from your house and then ground it according to the local rules. The manual says to consult with an electrical on proper grounding.

I've been told that I can run an 10 AWG wire to my water meter. Forget about google, only way that you will find out, is either contact your local NOAA office, the Coast Guard, which can explain better to you on proper installation.

To make things easy, do not ground to your water meter, since it violates the proper method of guarding against possible electrocution, or travel of electrical charge to the house. The proper info is contained in the NEC, and also your local code office can tell you the proper method for your area in grounding to Earth Ground. Most case it will be direct to your ground rod and #10 is IMO is too small in most case so #6 will handle it but before you do anything run this by electrical inspector or other proper personal with the correct information to do this. Gregzoll have good answer there and do as he mentions plus my comment above before you do anything else check with them first to see excitably what the requirement.

You will not be able to provide adequate grounding to protect against a direct lightning strike. Instead, you will be protecting against nearby strikes and atmospheric charge (St. Elmo's fire, in the extreme).

This is NOT a supplemental grounding electrode for the purposes of your home's electrical system. Its only purpose is to drain atmospheric charge from the metal pole on your roof and keep it at close to the same potential as the earth in case of a nearby lightning strike.

Make sure all the electronic equipment that connects to the weather station is properly grounded (NOT to the new ground rod), and preferably has lightning suppression on the lines that run to the rooftop equipment. Following amateur radio practices for lightning protection would be wise.

There is a lot of information on the web about amateur radio antenna installation, almost all of which is applicable to your project. It will usually involve a down conductor connected to the mast down to a ground rod.

On air, it says it's good for 1/4 mile wow, I didn't realize how much loot these things cost. I'm installing a weather station for a local elementary school on my roof that the kids will be able to access over the Internet.

Because I'm paying for this out of my pocket my budget is very limited and Eva electrician I talk to wants to charge me a service call fee to come out and do the job properly and safely. Read art.810.820,250.50.these relate to antennas and masts.alto this art's are for CATV and radio, i think they apply to this situation.

I didn't think lightning protection electrodes were required (or ever intended!) MP I tend to agree with you but the reason for the bonding is to prevent “side flashing” or arcing to other parts of the grounding system.

This is one reason I suggested to the OP that he might want to install the device on a pole located away from the house. From a Code standpoint, the NEC has been relatively silent on the Code requirements that relate to lightning protection systems; however, the NEC requirements (Sections 250.60 and 250.106) cover the materials and bonding of the electrode of a power distribution system to the ground terminal of a lightning protection system on the same structure.

MP this is some good information you may want to check out http://www.lightningsafety.com/nlsi_lhm/IEEE_Guide.pdf If I was going to be installing something that expensive I would check with a local inspector what they require for your area.

Some number 4 insulated wire to a couple copper rods would not cost that much to be on the safe side. And I also added a grounding block inside before the cable went to the signal amplifier and splitter.

The size of the conductor does not really make a big difference. Grounding/bonding the system and Lightning protection with proper air terminals.

Wind speed and direction, Precipitation, Weather Underground access . I'm located in Canada and have read that some stations don't do particular well in very cold weather so any advice appreciated.

Hey all, I've wanted a weather station for some time, and just never had the money burning a hole in my pocket before. For best results, I think I'm going to want to put the weather station as far away from my house as possible, out at the back fence.

I'm trying to add my new weather station (Accurate Iris with Access) using a WordPress Weather Station plugin on my website instead of Week generated web files. Adding a weather station on WordPress with Accurate requires a clientraw.txt file.

What is the source type (I'm guessing it's via FTP as I'm not running a web server on Rasp. The instructions say to hold wind and pressure together for 5 seconds to put it in Wi-Fi broadcasting mode.

The location of your weather station is the most important part of installation. Your weather station should have good “fetch”, or distance from any other tall object.

The process of deciding how and where to install your weather station is called “Siting”. Siting is the single most important factor in ensuring accurate readings.

The most common error in installing a weather station is associated with misplacing the thermometer sensor. This way, your weather station can be placed in direct sunlight, with the thermometer located inside the radiation shield.

If you purchase from Ambient Weather, use coupon code “underground” to receive a 10% discount. A cheaper solution if you cannot use a radiation shield is to use a sheet of aluminum mounted about 6 inches from the thermometer.

This aluminum sheet should shield the sun at all times and have plenty of ventilation. Hence, make sure the humidity sensor is at least 50 feet away from the nearest tree or body of water.

The rain collector should be placed with at least 5 feet horizontal clearance from the nearest obstruction. Similar to a rain collector, the anemometer should reflect the wind patterns as if the instrument was placed in a large field.

You can purchase a tripod or arm mount for your weather station. The arm mount allows you to install the station on a fence or exterior wall, while the tripod can be placed on the ground or rooftop.

Generally speaking, black surfaces (asphalt, black shingles) measure warmer temperatures than lighter colored surfaces (gravel, gray shingles). Ideally, your weather station should be placed 5 feet over short grass or low shrubs.

The Metro is a highly accurate, durable, research-grade meteorological monitoring station, designed for a wide variety of demanding environmental applications. The MesoPRO™ is a highly accurate, durable, research-grade meteorological monitoring station, designed for a wide variety of demanding environmental applications.

The ET107 is an automated weather station designed for irrigation scheduling in turf grass and commercial agriculture applications. Rugged design, low power requirements, and long-distance communications methods allow modern weather stations to operate remotely for long periods without the need for human intervention.

Weather stations vary greatly in their level of sophistication and complexity, as well as their flexibility and ability to measure, monitor, and study weather and climate conditions. Automated weather stations measure and record meteorological variables over extended periods without the need for human intervention.

Automated weather stations offer the convenience of unattended, long-term monitoring at multiple remote locations, thereby reducing the time and cost associated with frequent measurements. The durability and low-power needs of some automated weather stations can make them an appropriate choice for harsh climates and remote locations.

For example, a simple automated weather station designed for limited personal use may be a self-contained unit. A more sophisticated research-grade automated weather station, on the other hand, may have several components that the organization individually selects to create a customized solution to meet their needs.

The transmitted electrical signal is often conducted through a sensor’s wires, which may require specialized connectors. Some common signal types include voltage, current, pulse, digital, and serial.

However, for the purpose of this discussion, our focus will be on general-purpose data loggers, which tend to offer more flexibility for an automated weather station’s application. For example, a flexible data logger is easy to install in the field for remote monitoring, is durable enough to withstand continued use outside, and has low-power needs for unattended applications.

In addition, the data logger can perform control operations, similar to a PLC or RTU. The signal output from the sensor must be compatible with the data logger input terminal to which it is connected.

These methods employ a variety of communication peripherals with onsite and telecommunication options. When a station is installed in a location without access to ac power, a rechargeable battery is typically used.

The number and size of the batteries needed depends upon the current drain (or power requirements) of the automated weather station (including telemetry), the maintenance interval, and the amount of solar power available during a given time interval (for example, 24 hours) at a given latitude to recharge the batteries. Sometimes wind turbines, fuel cells, or diesel or gasoline generators are used as charging sources.

To protect an automated weather station’s most sensitive components from the elements, a suitably sized environmental enclosure is typically used to house a data logger, communication peripheral, power supply, and some sensors. An automated weather station’s components, whether placed in an enclosure or directly exposed to the elements, are grouped together and physically supported by mounting them to a stable structure, such as a tripod, tower, or buoy.

To meet different measurement requirements, a variety of tripod and tower heights are available. These extreme environments include mountainous terrain, deserts, jungles, mines, oceans, and ice floes.

While automated weather stations can be compared and contrasted on many levels, the following are some primary characteristics that may be helpful for you to be mindful of: Quality It is important to note that different manufacturers do not use the same criteria for classifying automated weather stations.

Measurement quality (accuracy, precision, and resolution) Reliability Expected longevity in the field Accuracy is the ability of a measurement to provide a result that is as close as possible to the actual value.

Although an automated weather station’s quality is reflected in its accuracy, precision, and resolution, these characteristics are not directly correlated. For example, a simple station that records outside air temperature and humidity with low measurement quality (accuracy, precision, and resolution) may meet the data needs and low-cost requirements of a weather hobbyist.

On the other hand, an organization whose primary business or purpose is to obtain and distribute weather information may need a more sophisticated automated weather station with better measurement quality to record not only air temperature and humidity, but also barometric pressure, precipitation, wind direction, wind speed, and other parameters. The same is not true, however, for a national weather reporting agency that depends heavily on an automated weather station performing consistently day in and day out to deliver data for the prediction and reporting of severe storms.

A weather hobbyist who has spent a minimal sum for a personal station may not be concerned if it begins displaying erratic measurements or fails completely and needs to be replaced after a short period. In contrast, an organization whose primary business is to obtain, evaluate, and distribute weather data and has spent considerable resources for data acquisition will expect its automated weather station to be durable and provide long-term monitoring.

In addition, there is significant variability in the sensor compatibility of different data loggers. Both current and future needs for expand ability can be addressed by selecting a data logger and any necessary, compatible expansion modules, such as a multiplexer.

A flexible data logger enables the ease of removing and adding sensors as necessary to acquire the desired measurements when they are needed. It is important to note that the terms “portable” and “permanent” may be used to cover a breadth of automated weather stations that vary greatly in their sturdiness and stability.

Typically, a portable automated weather station is considered one that can be moved easily from one site location to another. Oftentimes, a portable station is installed using a tripod secured directly to the ground.

Some applications require a portable station that can be set up quickly to monitor weather conditions for a short period. For example, a portable automated weather station is used for prescribed burns to monitor the wind conditions and help ensure that fires remain controlled.

For example, after an analog station has been removed from its packaging, its only setup requirement may be to place it in the desired location. As another example, a digital or wireless station for a hobbyist requires a power source and perhaps minimal configuration of the display unit.

The rewired or preconfigured station has a set of components that have been configured by the manufacturer to work together, but some assembly for their connection may be required. For example, the data logger is housed inside an environmental enclosure that may or may not include connectors for attaching the sensors.

Furthermore, the connectors can vary as to their IP rating and ability to protect against the intrusion of foreign objects or substances. Custom stations A custom automated weather station comprises a collection of components that, while not fully integrated by the manufacturer, are 100 percent compatible to provide the specific functionality required for the intended application.

The manufacturer leaves the integration to the user to provide the highest degree of customization possible. Determining how to make these connections is dependent upon the specific sensors and data logger being used.

A sensor’s instruction manual or the data logger’s program may provide the specific wiring information. Selecting an automated weather station is an important decision that requires careful consideration.

For assistance with the selection process, review the detailed Purchase Considerations section. An automated weather station is built at the component level to provide an organization with the instruments it needs to meet its measurement objectives.

The versatility of an automated weather station is evidenced in your ability to add, remove, or substitute sensors or other peripherals as your data measurement and monitoring needs change. To assess the numerous research-grade automated weather station models and ultimately determine which components are the most suitable, you should first identify your application's needs and requirements.

Your familiarity with these items will help ensure that the automated weather station components you select will meet your compliance requirements. Selecting the appropriate sensors is a critical step for your organization to obtain the data it requires.

Review the manual for each sensor you will use to ascertain the type of data logger connection needed. If the number or types of sensors you will be using exceeds the inputs available on a data logger, you may be able to use a compatible expansion peripheral.

Campbell Scientific automated weather stations are modular, enabling the connection of a variety of sensor types and peripherals to customize a station that best meets your application's needs. Campbell Scientific instruments are reputed to provide high levels of accuracy, precision, and resolution in terms of measurement data.

Your automated weather station's location should be representative of the general area of interest that you would like to measure. If the components of your automated weather station are not designed for the environment in which they are located, the instruments may not perform as expected or stop working.

Quality and durability If the site for your automated weather station is exposed to icing, sand, blowing dirt, salt spray, snow buildup, high winds, hail, or heavy rain, ensure your station's components are durable enough to withstand these conditions. Man-made damage Consider how susceptible the site location is to man-made risks such as off-road vehicles, golf balls, or bullets.

As necessary, camouflage your automated weather station to make it less attractive to potential vandals. Wildlife interference Station performance and data accuracy can be affected by a bird that views a rain Gage as the perfect home for its new nest.

Water exposure If your automated weather station will be placed in a humid or wet environment, check that the components can handle the moisture level and possible corrosion from salt spray. You can protect your data logger and other sensitive components by housing them inside a sealed environmental enclosure.

A portable weather station can be moved easily among multiple sites that require infrequent or temporary monitoring and measurement. Ensure that the intended site location can spatially support the mounting of your selected automated weather station.

Programmable data loggers offer options for scheduling scans, as well as developing and running customized programs. Moreover, parameters such as the following may be calculated using the data provided by sensors: density altitude, dew point, evapotranspiration, heat index, and wind chill.

Data loggers can activate or shut down motors, gates, pumps, purifiers, valves, injectors, etc. In addition, a free, menu-driven, PC-compatible software package that simplifies the creation of data logger programs is available for download.

Storage capacity Selecting a data logger by memory size alone may not prove advantageous. Instead, it may be more beneficial to consider storage capacity in terms of how many readings the data logger can store.

It is possible for a data logger to have many kilobytes or megabytes of memory but only be able to hold a small quantity of readings. Non-volatile storage media, such as EEPROM and flash memory, are not affected when the power supply is disrupted; they will maintain their data.

Campbell Scientific offers numerous communication peripherals to assist with the data storage needs of your automated weather station. Remote or direct access If it is important for you to collect and view your data without having to visit your site, investigate the telemetry options available to you.

Another onsite option is to use an external data storage device with a memory card that can be transported and uploaded to a PC at an offsite location. For example, review the transmission distance or area of each option, as well as its applicable service requirements.

In addition, if an atypical event occurs, a data logger can be programmed to trigger an alarm (such as a phone call, bell, whistle, light, etc.) Personnel can use these devices to respond to prompts and messages from the data logger at the station site.

Instead of using a keyboard with display to interact with an onsite data logger, it may be possible to use a laptop computer. The power supply must be sufficient to handle the current drain of all the sensors, data logger, communication peripherals, and other equipment.

If your automated weather station includes equipment with a high current drain, such as cellular phones or satellite transmitters, select a large-capacity rechargeable battery pack. If your site has temperature extremes, and ac power is not available, consider using a rechargeable battery.

If your automated weather station is located at a site that receives minimal sunlight, ensure that you will have enough power supply for continuous monitoring. If your automated weather station will use an ac power supply, consider the benefits of a backup battery.

Campbell Scientific devices are designed to be low-power-consuming, and numerous power supply options are available. However, because a turnkey station requires very little or no configuration prior to usage, it can be set up quickly.

Consequently, it minimizes the wiring time and possibility of erroneously connecting a sensor to the wrong input terminal. Sensors can be added and removed as needed based on changes to research or project objectives, or funding.

Campbell Scientific offers turnkey, rewired or preconfigured, and custom automated weather stations. An automated weather station's components, whether housed in an enclosure or directly exposed to the elements, are grouped together and physically supported by mounting them to a structure, such as a tripod or tower.

If your automated weather station is in an area with uneven terrain, consider using a tripod with individually adjustable legs. For example, if the mounting equipment needs to be transported in a pack up to a summit, review its weight and length specifications.

Campbell Scientific offers a wide variety of enclosure and mounting options. As with any high-performance equipment, some level of maintenance (cleaning, calibration, and replacement) of the various automated weather station components is routinely required.

Planning ahead Review the recommended calibration and maintenance frequency of your station components so you can create a maintenance budget in terms of employee resources, travel time for site visits, and equipment costs. Determine which maintenance tasks can be handled onsite, such as with a field calibration tool, and which require equipment to be sent to the manufacturer.

If downtime without data is not acceptable, have sufficient replacement parts (such as batteries) and backup equipment on hand. Campbell Scientific provides factory service, traceable calibrations, and replacement parts for many of its automated weather station components.
