Unit Earth
Description
Unit Earth is a soil moisture sensor used for collecting moisture in soil or similar materials. The sensor has two measurement probes that are inserted into the soil to be measured. Since higher moisture content results in better conductivity, the potential difference between the two probes is measured and converted via ADC, and the detection result is sent to the M5Core. The Unit also integrates a 10K adjustable resistor for adjusting the detection threshold.
