Description

This soil moisture sensor module is designed for detecting the water content in soil, making it ideal for smart gardening, automatic irrigation systems, and DIY electronics projects. The module offers both digital and analog outputs, allowing for simple on/off control or precise moisture level readings. Sensitivity is adjustable via the onboard blue potentiometer.

Use it with microcontrollers like Arduino, ESP32, or Raspberry Pi to build a smart garden system that automatically waters your plants when the soil gets dry.
