Module Capacitive Soil Moisture Sensor v1.2 Accurate for Arduino

Capacitive soil moisture sensor V1.2 for Arduino, Raspberry Pi, ESP8266 and ESP32

Capacitive soil moisture sensor V1.2 is an innovative measurement solution. It uses capacitive sensing, which effectively eliminates the corrosion problem known from traditional resistive sensors and provides much longer service life.

The integrated voltage regulator enables trouble-free operation over a wide supply range from 3.3 V to 5 V. The sensor is fully compatible with popular microcontroller platforms-it works great with Arduino, Raspberry Pi (ADC conversion module required), as well as ESP8266 and ESP32. The module allows continuous plant monitoring by accurately checking substrate moisture levels. It is an excellent solution for smart pots and IoT projects.
