About this item

The DFRobot Gravity Analog Capacitive Soil Moisture Sensor is a robust, reliable sensor designed to accurately measure soil moisture levels using capacitive sensing technology. Unlike traditional resistive sensors, which suffer from corrosion over time due to direct contact with soil, this sensor features a corrosion-resistant design, significantly improving durability and longevity for long-term agricultural and gardening applications. This sensor outputs an analog voltage proportional to the soil moisture content, which can be easily read by any microcontroller with an analog input, such as Arduino, ESP32, or Raspberry Pi with ADC. It is perfect for smart irrigation systems, environmental monitoring, and plant care automation, helping users optimize watering schedules and conserve water. With its high sensitivity and fast response time, it provides precise and real-time soil moisture data without the degradation issues typical of resistive sensors. The Gravity interface makes it plug-and-play, simplifying integration for both beginners and advanced users. Operating at a wide voltage range and low power consumption, this sensor suits various battery-powered or continuous monitoring projects. Overall, the DFRobot Gravity Analog Capacitive Soil Moisture Sensor combines accuracy, durability, and ease of use, making it an excellent choice for any soil moisture sensing application.
