The Vaisala WXT520 multi-parameter weather sensor simultaneously measures wind speed and direction, liquid precipitation, barometric pressure, temperature, and relative humidity with an unparalleled combination of performance and value. The sensor consumes little power and has no moving parts, making it ideal for remote weather stations. A number of options are available, including a heated version, bird deterrent kit, USB service cable, lightning surge protector, and M12 cable connector assembly.

All measurements are based on proven Vaisala technology, including the PTU module for barometric pressure, temperature, and humidity; the WINDCAP sensor for wind speed and direction; and the RAINCAP sensor for rainfall, rain intensity, and duration. The precipitation measurement detects the impact of individual rain drops, which is proportional to the volume of the drops. The signal from each drop is converted directly to the accumulated rainfall.

The Vaisala WXT520 multi-parameter weather sensor housing with mounting kit is water-resistant to IP66, completely protecting the internal components from dust and low-pressure jets of water. The sensor includes an SDI-12 output for interfacing with NexSens iSIC and SDL data loggers. Data collection options include direct-connect, landline phone, cellular, radio, Ethernet, WI-FI, and satellite telemetry. NexSens iChart Software is a Windows-based program for interfacing both locally (direct-connect) and remotely (through telemetry) to a NexSens data logger or network of data loggers.

Predicting Wildfire Movement With Multiparameter Weather Sensors

California wildfires in 2016 have been tough to contend with. And the state’s fight against blazes has been a recurring storyline in recent years. But perhaps a less-covered angle is the new ways through which government agencies and private interests have come together to protect infrastructure and life. We have reported on the expanding camera networks throughout California and other western states that are helping first responders address potential fires more quickly. But spotting wildfires as they start is just one side of the coin. There is also an urgent need to predict their movements, and weather conditions are key in that effort. Wind is especially important, as its shifts can change the course of a blaze. Humidity and temperatures influence fire dynamics too.

Camera-equipped Antarctic weather stations track climate, icebergs and penguins

There are ways to keep 10-hour work days installing weather monitoring stations in the bitter cold of Antarctica tolerable. The occasional break for tea to warm up and a Gore-Tex jacket to block the wind help, says Ronald Ross, an Australian-based independent electrical consultant who finds himself out on the ice of the southernmost continent once a year. While the benefits of a hot beverage and a good coat are obvious, there are other important protective steps that aren't. "You're lathering on a lot of sun tan lotion, which seems a little odd out in such a cold area," Ross said. "But you get fried. Without suntan lotion you'd be totally red within fifteen minutes. It's that intense when the sun is out with the reflection off the snow.

Village Green Project builds air quality awareness with monitoring park bench

The U.S. Environmental Protection Agency is on a mission to make air quality monitoring cheaper, easier and more accessible through the implementation of innovative new monitoring stations. The Village Green Project is a new initiative from the EPA that seeks to increase the scope of air quality monitoring by seamlessly incorporating monitoring devices into community settings. Led by Gayle Hagler, an environmental engineer at the EPA Office of Research and Development, an EPA design team has constructed a prototype that combines the ability to monitor ozone and fine particulate matter as well as wind speed, wind direction, temperature and humidity all into the functional design of a park bench.
