The capacitive sensing area forms one plate of a capacitor, with the surrounding soil acting as the dielectric medium. As soil moisture increases, the dielectric constant rises, which increases the capacitance. The onboard circuit converts this capacitance change into an analog voltage - wetter soil produces a lower voltage, and drier soil produces a higher voltage. Simply connect the output pin to an analog input on your microcontroller, read the ADC value, and map it to a moisture percentage through calibration.\u003c\/p\u003e\n\n\u003ch2\u003eProject Ideas\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic Plant Watering System:\u003c\/strong\u003e Combine with a relay module and a water pump to build a self-watering system that irrigates plants only when soil moisture drops below a set threshold - perfect for home gardens, balcony planters, or greenhouses.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIoT Smart Agriculture Monitor:\u003c\/strong\u003e Pair with an ESP32 or ESP8266 to transmit real-time soil moisture data to cloud platforms like Blynk, ThingSpeak, or Home Assistant.
