Design and Construction
The Capacitive Soil Moisture Sensor V2.0 features a compact sensing board with a corrosion-resistant PCB coating for improved durability in soil environments. Its capacitive sensing structure allows moisture to be detected without depending on exposed metal electrodes.
The simple three-pin interface makes the sensor easy to connect to development boards and microcontrollers. Its compact construction allows it to be inserted into soil near plant roots for convenient moisture monitoring.
Working Principle
The sensor works by detecting changes in the capacitance of the soil as its moisture content changes. Water in the soil affects the dielectric properties surrounding the sensing area, causing a corresponding change in capacitance.
The sensor converts this change into an analog voltage output. A connected microcontroller or ADC can read this signal and use the measured value to determine relative soil moisture conditions.
The analog readings can be calibrated according to the soil type and application to establish suitable dry, moist, and wet ranges.
