M5 Stack Earth Moisture Unit Drone Kits SMA connector for external antennaM5 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.
