Description
M5 Stack Earth Moisture Unit
EARTH unit is a Soil Moisture Sensor for measuring the moisture in the soil and similar materials.
The soil moisture sensor usage is pretty straight forward, 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 using the ADC. Inside this Unit, we’ve added extra potentiometers to change the measurement range.
Note: Electrode of the unit is not anti-corrosive, or waterproof, for POC purposes only. Please, do NOT put it in a humid environment for a long while.
