Overview
Take the guesswork out of watering your plants!
This Arduino Soil Moisture Sensor Module detects soil humidity levels in real time, allowing you to automate your plant watering system. Ideal for DIY enthusiasts and smart gardening projects, it works perfectly with Arduino, Raspberry Pi, and other microcontroller platforms.
Key Benefits
- Build a Smart Watering System: Automatically control pumps or relays based on soil moisture levels — no more over or under-watering.
- Dual Output Design: Provides both Digital Output (DO) for threshold-based alerts and Analog Output (AO) for accurate sensor readings.
- Wide Compatibility: Works seamlessly with Arduino, microcontrollers, and 3.3V–5V development boards.
- Adjustable Sensitivity: On-board potentiometer lets you fine-tune the detection threshold for different soil types.
- Visual Indicators: Red Power LED and Green Output LED provide instant status feedback.
