The Capacitive Soil Moisture Sensor is a compact and corrosion-resistant solution for monitoring soil moisture levels in plant pots, gardens, and automated irrigation systems. Unlike traditional resistive soil moisture sensors that expose conductive electrodes directly to the soil, this sensor uses capacitive sensing, helping reduce electrode corrosion and improving long-term usability.
The sensor produces an analog output voltage that changes according to the moisture level detected around the sensing area. This analog signal can be connected directly to an analog input of a compatible microcontroller and converted into a relative soil moisture reading through suitable programming and calibration.
Its compact probe-style design makes it easy to insert into soil without requiring complicated installation. The sensor is particularly useful for automatic plant watering systems, where a microcontroller can monitor soil moisture and activate a water pump when the soil becomes too dry.
The module can be used with popular development platforms such as Arduino, ESP32, STM32, and other boards with suitable analog input capability.
