A digital infrared proximity sensor with an adjustable detection range of 0–200 cm. It uses diffuse IR reflection to detect objects or people, outputting a digital high signal when something enters the sensing zone and returning to low when cleared — ideal for smart home, security, robotics, and automation applications.

Detection distance is easily configured using the onboard button: press and hold while the indicator flashes, then position the target at your desired distance. The sensor automatically saves the calibration. A standard 3-pin digital cable connects directly to Arduino I/O expansion boards.
