Capacitive Soil Moisture Sensor Not Easy To Corrode Wide Voltage Module For Arduino

Description:
 
This capacitive soil moisture sensor is distinguished from most resistive sensors on the market and uses capacitive sensing to detect soil moisture. The problem that the resistance sensor is easily corroded is avoided, and its working life is greatly extended.
 
The sensor has a built-in voltage regulator chip that supports a 3.3-volt working environment, which means it works even on a 3.3V Arduino control board. A miniature PC such as the Raspberry Pi
