This Earth Moisture Sensor unit from M5 Stack is a Soil Moisture Sensor for measuring the moisture in the soil and similar materials. It is compatible with M5 Cores and communicates with the M5 Core with the grove cable.

The soil moisture sensor is pretty straight forward to use. The two large exposed pads function as probes for the sensor, together acting as a variable resistor. The higher moisture that is in the soil means the better the conductivity between the two so that the sensor will result in lower resistance, and a higher SIG out.

You can read the moisture in the soil by ADC. Inside this Unit, we put an extra potentiometer to change the measurement range.
