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.

Configuring Input

Click on the Child Inputs. The child inputs corresponds to the below:

• Child input 0 = Wind Speed m/s

• Child input 1 = Wind Direction

• Child input 2 = Air Temperature °C

• Child input 3 = Average Wind Speed (Meridional) m/s

• Child input 4 = Average Wind Speed (Zonal) m/s

• Child input 5 = Maximum Wind Gust m/s
