Soil Moisture Hygrometer Humidity Sensor Module For Arduino

The Soil Moisture Sensor helps detect soil moisture levels, making it ideal for automatic plant watering systems.

🔹 Key Features

✔ Detects Soil Moisture – Outputs HIGH when dry, LOW when wet.
✔ Adjustable Sensitivity – Fine-tune using the blue potentiometer.
✔ Dual Output Mode –

• DO (Digital Output): Simple 0 or 1 signal (dry/wet).
• AO (Analog Output): More accurate moisture level readings.
  ✔ Voltage: Works with 3.3V – 5V power.
  ✔ Indicator LEDs:
• Red = Power ON
• Green = Digital output status

🔹 Wiring Guide (to Arduino)

✅ AO gives precise moisture levels (0-1023)
✅ DO gives simple wet/dry status (0 or 1)

🔹 Applications

✔ Automatic Plant Watering – Triggers a pump when soil is dry.
✔ Soil Moisture Monitoring – For gardens, farms, and greenhouses.
✔ Smart Irrigation Systems – Save water by watering only when needed.
