What is a Resistive Soil Moisture Sensor?
A resistive soil moisture sensor is a simple electronic device used to measure the moisture level in the soil. It works by detecting changes in the resistance between two conductive plates embedded in the soil. The wetter the soil, the lower the resistance, and vice versa.
The sensor module includes an LM393 comparator, which allows it to output either analog or digital signals, making it compatible with most microcontrollers like Arduino, ESP32, NodeMCU, and more.
Features of Soil Moisture Sensor with LM393 Module

Working Principle
The probes on the sensor act as electrodes and are inserted into the soil. Depending on the water content, the conductivity between the probes changes. The LM393 comparator on the module reads this signal and provides:
- Analog Output (AO): Continuous values to measure precise moisture levels.
- Digital Output (DO): High or Low signal based on a user-defined threshold using the onboard potentiometer.
You can use these readings to trigger alarms, relays, or automate water pumps for smart irrigation!
