Capacitive Soil Moisture Sensor

The Capacitive Soil Moisture Sensor is a reliable and durable solution for monitoring soil moisture in smart agriculture, automated irrigation, and IoT projects.

Unlike traditional resistive moisture sensors, this capacitive version does not rely on exposed metal probes, which significantly reduces corrosion and ensures more stable, long term measurements. That makes it ideal for permanent installations in pots, gardens, greenhouses, or research setups.

The sensor outputs an analog voltage (0-3V) that changes depending on soil moisture levels. Simply connect it to the analog input of your microcontroller and start reading real time soil data for your automation or monitoring system.

Whether you're building a smart watering system, a remote environmental monitoring node, or an educational STEM project, this sensor is a dependable choice for makers and educators alike.
