About this item

The DFRobot Gravity Digital Adjustable Infrared Proximity Sensor is a compact and easy-to-use sensor designed to detect the presence of objects without physical contact. Using infrared (IR) reflection technology, it can reliably sense objects within a range of 3 to 80 cm, making it ideal for robotics, automation systems, obstacle detection, and interactive projects. One of the key features of this sensor is its adjustable detection distance, which can be fine-tuned using the onboard potentiometer. This allows users to optimize the sensor’s sensitivity according to different environments or application requirements. The sensor provides a simple digital output (HIGH/LOW) that can be easily read by any microcontroller, such as Arduino, ESP32, or Raspberry Pi. Designed with a Gravity interface, the module offers plug-and-play compatibility, reducing wiring complexity and ensuring stable, reliable connections. It also features onboard indicators for power and output status, making debugging and setup faster. Its compact form factor, low power consumption, and real-time response make it well-suited for smart systems, automatic doors, object counters, and interactive art installations.
