Capacitive Soil Moisture Sensor (Corrosion Resistant) ESP 07 Cover distance of about 120°The Capacitive Soil Moisture Sensor (Corrosion Resistant) is a soil moisture sensor based on capacitance changes. Compared with resistive sensors, capacitive sensors do not require direct exposure of the metal electrodes, which can significantly reduce the erosion of the electrodes, it is considered Corrosion Resistant. It is important to note that this sensor can only qualitatively test the humidity of the soil and cannot measure quantitatively. When
