## Description

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. Key Features Adjustable Detection Range – 0–200 cm, set via onboard button Digital Output – Active-high switch signal IP67 Waterproof – Suitable for outdoor and harsh environments Wide Detection Angle – 30–40° cone 3-Pin Interface – Plug directly into Arduino expansion boards Specifications Power Supply: 5 V Detection Distance: 0–200 cm (adjustable) Output: Digital switch (active-high) Detection Angle: 30–40° cone Operating Temperature: −10 to 60 °C Storage Temperature: −20 to 70 °C Waterproof Rating: IP67 Ideal For Smart home and security systems Robot obstacle detection Automated door and gate triggers Industrial presence sensing Resources Product wiki
