Hobo S-WDA-M003 – Onset
Wind direction sensor, compatible with the USB data loggers stations or with the web-based monitoring systems for remote communication
The wind direction smart sensor is a research-grade plug-and-play sensor for measuring and logging wind data. It provides average wind direction for the measurement interval. This highly-durable wind vane has a drip overhang for anti-icing. Its shielded stainless-steel ball bearings and static-dissipating housing provide a long sensor life. The sensor calculates a unit vector average of the wind direction, providing data directly in degrees.
This is a plug-and-play smart sensor, who is compatible with RX, H21, H22, and U30 loggers (stations). The wireless Wind Speed and Direction sensor is available for use with the HOBOnet Field Monitoring System and note: an M-CAA full cross arm or M-CAB half cross arm is required for mounting. This sensor operates in indoor and outdoor environments and the S-WDA-M003 sensor supports the following measurement: wind.
Technical specifications
