Description
The sensor unit measures moisture in soil and similar materials.
The two large exposed pads function as probes for the sensor,
together acting as a variable resistor.
The higher the moisture, the better the conductivity, the higher the out-
put signal value. Moisture can directly be read by ADC.
Through the potentiometer you can change the measuring range.
