The Capacitive Soil Moisture Sensor is a highly reliable, corrosion-resistant sensor designed to measure the moisture content of soil using capacitive sensing technology. Unlike resistive sensors, it avoids electrolysis, ensuring long lifespan and stable readings. Its analog voltage output varies with the soil’s water content, making it an excellent choice for smart farming and automated irrigation systems. DESCRIPTION Capacitive sensing for long-term durability and corrosion resistance Stable analog output proportional to soil moisture level Wide operating voltage range (3.3V–5V) compatible with Arduino, ESP32, and Raspberry Pi Waterproof PCB design for outdoor and greenhouse applications Easy-to-interface 3-pin connector (VCC, GND, A out) APPLICATIONS Smart irrigation and plant monitoring systems Precision agriculture and greenhouse control Soil and crop research experiments IoT-based environmental monitoring
