Meter Group ATMOS22 (Decagon DS2) - Wiring
The Decagon DS-2 is a rugged sonic anemometer that measures wind speed, wind direction and temperature (unshielded) to provide 6 outputs; Wind Speed, Wind Direction, Average Wind Speed (Meridional) m/s, Average Wind Speed (Zonal) m/s and Maximum Wind Gust m/s along with Air Temperature °C
It uses very little power and needs no calibration (see Decagon site for more details).
See below wiring on DS-2 end:
Refer to SDIM12 Connector wiring to connect the DS-2 to a Wildeye loggers SDI12 input.
