Soil Moisture Sensor Module

The Soil Moisture Sensor Module is designed to detect the water content in soil and trigger actions based on dryness levels. Ideal for automatic plant watering systems, this sensor helps ensure your plants are never over- or under-watered. It outputs a digital signal (dry/wet status) and can be easily integrated into Arduino, ESP32, or Raspberry Pi projects.

Perfect for smart gardening, greenhouses, or hobbyist experiments, this module is both affordable and reliable for real-time soil monitoring.

✅ Key Features:

💧 Detects soil moisture level with dual probes

🎚️ Adjustable sensitivity using onboard potentiometer

📦 Digital output (wet/dry) for easy microcontroller interfacing

🌿 Suitable for automatic irrigation systems

🔌 3-pin interface: VCC, GND, D0
