What's In The Box:

HOBOnet Ultrasonic Wind Speed & Direction Sensor

Zip ties and screws for mounting

A wireless ultrasonic wind speed & direction sensor that works with HOBOnet. Compact and rugged, with no moving parts, this ultrasonic sensor can measure very low wind speeds, down to 0.4 m/s (compared to 1.0 m/s for our mechanical sensors). HOBOnet wireless sensors communicate data directly to the HOBO RX3000 or the HOBO MicroRX station or pass data through other wireless sensors back to the central station. They are preconfigured and ready to deploy, and data is accessed through HOBOlink, Onset's innovative cloud software platform.
