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