MAKERFACTORY MAKERFACTORYM5 Stack Earth Moisture sensor

The M5 Stack Earth is a soil moisture sensor for measuring the moisture in the soil and similar materials. The humidity sensor is very easy to use. The two large, exposed pads serve as probes for the sensor and act together as a variable resistor. The higher the moisture in the soil is, the better the conductivity between the two, so that the sensor a lower resistance and a higher SIG value. You can use the moisture in the soil by ADC reading. This device is additionally a potentiometer is installed to the measuring range. This text is machine translated.
