HOBO Ultrasonic Wind Speed and Direction Smart Sensor
Overview
The Ultrasonic Wind Speed and Direction Smart Sensor is compact and rugged with no moving parts. Because this sensor is ultrasonic it is able to measure very low wind speeds, down to 0.4 m/s (compared to 1.0 m/s for our mechanical sensors). As with all Onset smart sensors, this sensor is plug-and-play with HOBO stations (RX3000, USB Micro Station, H22, and the U30-NRC). Because it is automatically recognized by HOBO stations, there is no need for programming, resulting in fast and easy deployment. The sensor is powered by its own built-in solar panel.
