Digital Adjustable Infrared Proximity Sensor 3–80 cm Range

The Digital Adjustable Infrared Proximity Sensor is a compact module designed for detecting objects within a 3–80 cm range. It outputs a digital signal compatible with Arduino and other microcontrollers, allowing easy integration in robotics, interactive media, and industrial automation applications. The detection distance is adjustable via a screw on the sensor, providing flexible calibration for different environments. Operating at 5 V with a current of 100 mA, the module measures 45 × 18 × 18 mm, making it suitable for both small-scale and prototype projects. Its infrared sensing technology is optimized for indoor use, providing reliable wall detection, obstacle avoidance, and trigger system functionality.
