Ultrasonic Wind and Weather Station

Ultrasonic wind, temperature, relative humidity and pressure sensor has no moving parts to wear out.

Maretron's outdoor weather station measures wind speed and direction, air temperature, barometric pressure, and relative humidity. The wind measurement is performed using ultrasonic sensors, which means there are no moving parts to wear out or to get caught in the rigging.

The WSO100 accurately measures wind speed and direction even when tilted, making it ideally suited for heeled sailboats or powerboats operating in pitching and rolling seaways.

When used with Maretron displays (DSM200/DSM250/ N2KView®), you can view apparent wind speed and direction, humidity, air temperature, barometric pressure (with graphs to see trends), wind chill factor, heat index, and dew point. If you add speed through water (DST100), GPS (GPS100) and compass (SSC200), you can view true vessel referenced wind speed and direction as well as ground referenced speed and direction.
