SOIL Moisture SENSOR

The Soil Moisture Sensor Module is designed to measure the moisture content of soil by detecting its electrical conductivity. It consists of a soil moisture probe and a control module with both analog and digital outputs, making it ideal for automatic plant watering systems, smart agriculture, gardening, and Arduino-based projects.

Features

• Measures soil moisture content
• Analog and digital output signals
• Adjustable sensitivity using onboard potentiometer
• LM393 comparator-based control circuit

Specifications

• Sensor Type: Resistive Soil Moisture Sensor
• Operating Voltage: 3.3V–5V DC
• Output Type: Analog (AO) and Digital (DO)
• Comparator IC: LM393
• Interface: 4-Pin (VCC, GND, AO, DO)

Pin Configuration

1. VCC – 3.3V to 5V Power Supply
2. GND – Ground
3. AO – Analog Output (Moisture Level)
4. DO – Digital Output (Threshold Adjustable)
