WatermarkHolder_154x300 Watermark sensor measures soil water tension. As the tension changes with water content the resistance changes as well. That resistance can be measured using the sensor. The sensor consists of a pair of highly corrosion resistant electrodes that are imbedded within a granular matrix. The sensor is a resistive device that responds to changes in soil moisture.
Can be used with CaipoBase and CaipoWave.
