8. Module Size: Approx. 60mm × 20mm
9. Cable Length: ~20cm (varies by version)

The Soil Moisture Sensor Module is a simple and effective sensor that measures the moisture level of soil to help automate watering systems and monitor plant health. It uses two probes to sense the resistance of the soil, which changes with water content — higher moisture means lower resistance.

This module provides both analog and digital outputs, making it compatible with Arduino, ESP32, NodeMCU, and Raspberry Pi. The onboard LM393 comparator ensures accurate digital output, and the potentiometer allows you to adjust the moisture detection threshold easily.

Widely used in smart agriculture, gardening, and hydroponic systems, this sensor helps conserve water and maintain ideal plant conditions.
