The Soil Moisture Sensor Module with Resistive Probe is designed to measure the moisture level in soil by detecting changes in electrical resistance. As the soil becomes wetter, conductivity increases, allowing the sensor to determine moisture levels.
This module supports both analog and digital outputs, making it ideal for use with Arduino and other microcontrollers. It is widely used in smart irrigation systems, plant monitoring, and agricultural automation projects.
