Soil Humidity / Moisture Sensor (New Type - Capacitive Sensor) 530 Access control (hotelsA soil moisture sensor can read the amount of moisture present in the soil surrounding it. It is ideal for monitoring garden, or your plant's water level. This is a must have tool for a connected garden. This new type capacitive soil humidity sensor differs from other resistive sensors, adopting capacitive sensing principle to detect soil humidity. Since the circuit is not exposed at the detected end, the corrosion problem of sensor is avoided,
