The Capacitive Soil Moisture Sensor is an advanced and reliable sensor module designed to measure the moisture level in soil by detecting changes in capacitance. Unlike traditional resistive soil moisture sensors, it does not use exposed metal probes, making it more resistant to corrosion and providing longer operational life.
This sensor provides an analog output signal that can be easily read by Arduino, ESP32, Raspberry Pi, and other microcontroller platforms. It is ideal for smart agriculture, automatic irrigation systems, and IoT-based plant monitoring projects where accurate soil moisture measurement is required.
With its compact design, low power consumption, and stable performance, the Capacitive Soil Moisture Sensor is suitable for both educational projects and professional environmental monitoring applications.
