Model FFWETPos 1, 2 or 3 Probes -Poseidon Multi Depth WET Sensor

The Poseidon WET sensor can be used in any soil and substrate type. The measurement principle is based on 15 MHz TDR capacitive sampling. The sensor has a flexible sensing depth up to 2 meters. The FireFly platform node should be connected via the connector cable and takes care of the data transmission. On the connected FireFly platform sensor additional options like PAR-light or GPS can be added (for details: see FireFly FF02 specifications). For Volumetric Water Content (VWC) representation, soil/substrate-specific calibration is needed. We advise to trigger irrigation on permittivity and not to perform a VWC conversion.
