What it does
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
Good to know
- 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
