Keyestudio New Type Soil Humidity Sensor Module For Arduino

This new type capacitive soil humidity sensor differs from other resistive sensors, adopting capacitive sensing principle to detect soil humidity.

It is divided into the signal end and the detected end. When it is inserted into soil, the signal end will output analog value. The segmented the wire connection and casing pipe enhance its waterproof performance.

Since the circuit is not exposed at the detected end, the corrosion problem of sensor is avoided, extending life expectancy.

The built-in chip supports 3.3~5.5V working environment, Arduino, ESP32, micro:bit and controller. As to mini PC, you need an ADC module (analog signals are converted into signals)
