Soil Moisture Sensor Module (Soil Humidity Sensor)

The Soil Moisture Sensor Module is a simple and effective sensor designed to measure the moisture content of soil. It uses a two-probe resistive sensor to detect changes in soil conductivity and provides both analog and digital outputs for easy interfacing with Arduino, ESP32, Raspberry Pi, STM32, and other microcontrollers. It is widely used in automatic irrigation systems, smart agriculture, and environmental monitoring applications.
