Description

🌱 Key Features

✔ No Coding Needed – Works with analog voltmeters or relay modules
✔ Analog Output – 0–3V (dry to wet) for direct meter reading
✔ Digital Threshold – Adjustable HIGH/LOW trigger (via potentiometer)
✔ Corrosion-Resistant Probes – Long-lasting in soil
✔ Low Power – Runs on 3.3V–5V DC (battery-friendly)


🔧 How to Use (Without Arduino/Microcontrollers)

Option 1: Analog Voltmeter Display

  1. Connect:

    • VCC → 3V/5V Battery (+)

    • GND → Battery (−)

    • AO → Analog voltmeter (0–3V/5V range)

  2. Read:

    • 0V = Bone dry | 1.5V = Moist | 3V = Saturated

Option 2: Trigger a Buzzer/Relay

  1. Connect:

    • VCC → 5V Power

    • GND → Ground

    • DO → Relay module/buzzer

  2. Adjust:

    • Turn the blue potentiometer to set the moisture threshold.

    • LED turns on when soil is too dry/wet (depends on wiring).
