-
Sensor Type: Capacitive moisture sensor – detects soil moisture levels without corrosion-prone exposed electrodes.
-
Operating Voltage: 3.3V to 5V DC – fully compatible with Arduino, ESP32, Raspberry Pi, and similar platforms.
-
Output:
-
Analog Output (AO): Varies based on moisture content (lower voltage = wetter soil).
-
Some versions include Digital Output (DO) with adjustable threshold (via potentiometer).
-
Corrosion Resistant: Unlike resistive sensors, this module uses capacitive sensing – making it more durable and long-lasting.
-
Onboard Components:
-
Power indicator LED
-
Optional comparator IC (on some models) for digital output
-
Low Power Consumption: Ideal for battery-powered and long-term monitoring systems.
-
Compact & Lightweight: Slim PCB design makes it easy to insert into soil or plant pots.
