Soil Moisture Sensor Module for Arduino, Raspberry Pi & Smart Farming Projects

The Soil Moisture Sensor Module for Arduino, Raspberry Pi & Smart Farming Projects measures volumetric water content in soil using electrical resistance. An essential component for smart irrigation, automated farming, and plant care systems.

Key Features

• Soil moisture detection via electrical resistance measurement
• Analog output proportional to moisture level
• Digital output with adjustable threshold via potentiometer
• Corrosion-resistant probe for longer lifespan
• Adjustable sensitivity for different soil types
• 3.3V-5V operation compatible with all microcontrollers
• Low power consumption for battery-powered field sensors

Technical Specifications

Applications

• Smart farming and automated irrigation systems
• Plant monitoring and care automation
• Greenhouse control and climate management
• Garden automation and self-watering systems
• Agricultural research and soil analysis
• Indoor plant care and hydroponics

Important Notes

• Resistive probes corrode over time – capacitive sensors last longer
• Calibration required for different soil types
• Insert probe to consistent depth for comparable readings
• Digital output threshold should be set after testing in target soil
• Not for use in pure water or non-soil substrates
