The Decagon VP-4 is a rugged multi-parameter probe used in weather, microclimate and evapotranspiration studies providing outputs of Vapour Pressure, Temperature °C, Relative Humidity RH and Atmospheric Pressure (see Decagon site for more details).
See below wiring on VP-4 end:
Refer to SDIM12 Connector wiring to connect the VP-4 to a Outpost logger SDI12 input.
