S-WCG-M003 Sensor

Ultrasonic Wind Speed and Direction Smart Sensor

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.

Interested in wireless sensors? The wireless Wind Speed and
Direction sensor is available for use with the HOBOnet Field
Monitoring System.

Supported Measurements:

Wind

Key Advantages:

Compact and rugged with no moving parts
Plug-and-play with HOBO stations
No starting threshold – suitable for low wind speeds
No wind direction dead band – accurate wind data in all directions
Powered by its own built-in solar panel
Affordably priced
