Soil Moisture Sensor Module

Resistive Soil Moisture Sensor & Irrigation Module

The soil moisture sensor utilizes two exposed nickel-plated prongs inserted into agricultural soil. Moisture acts as an electrolyte, reducing electrical resistance between the probes to provide analog volumetric water content measurements for smart automated irrigation.

Specifications

• Operating Voltage: 3.3V to 5.0V DC
• Outputs: Analog moisture voltage (AO) and Digital dry/wet alarm (DO)
• Current Consumption: < 20 mA
• Sensitivity Adjustment: Onboard multi-turn potentiometer
• Applications: Smart plant watering systems, agricultural moisture logging
