Wind speed, direction, barometric pressure, temperature, precipitation and humidity

The Hanwell  weather sensors provide a range of high performance, compact and economical solutions to weather monitoring for outdoor environments. The Vaisala weather transmitter WXT520 measures barometric pressure, humidity, precipitation, temperature, and wind speed and direction. The sensor uses ultrasound to determine horizontal wind speed and direction and the barometric pressure, temperature, and humidity measurements are combined in the PTU module using capacitive measurement for each parameter.

The sensor is immune to flooding, clogging, wetting and evaporation losses and has the capability of detecting impact or individual rain drops.
