Soil Moisture Detection Humidity Sensor
60.00 EGP
This soil moisture sensor is designed for simple, code-free operation, making it perfect for hobby gardeners, DIY irrigation, and educational projects. Just connect to a battery-powered display or relay to monitor soil hydration without programming!
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
-
Connect:
-
VCC → 3V/5V Battery (+)
-
GND → Battery (−)
-
AO → Analog voltmeter (0–3V/5V range)
-
-
Read:
-
0V = Bone dry | 1.5V = Moist | 3V = Saturated
-
Option 2: Trigger a Buzzer/Relay
-
Connect:
-
VCC → 5V Power
-
GND → Ground
-
DO → Relay module/buzzer
-
-
Adjust:
-
Turn the blue potentiometer to set the moisture threshold.
-
LED turns on when soil is too dry/wet (depends on wiring).
