## Description

A digital infrared proximity sensor with adjustable detection range from 0 to 200 cm. Outputs a simple digital signal — HIGH when an obstacle is detected, LOW when clear. The detection threshold is adjustable via a rear-mounted screw, making it easy to tune for different applications. Features the DFRobot Gravity interface (XH2.54 3-pin) for plug-and-play connection with Arduino and compatible IO expansion shields. Operates on 3–5 V, making it suitable for both 3.3 V and 5 V microcontrollers. Specifications Detection Range – 0–200 cm (adjustable) Signal Type – Digital (PNP normally open) Output – LOW = no obstacle, HIGH = obstacle detected Operating Voltage – 3–5 V Interface – Gravity XH2.54 3-pin Operating Temperature – −15°C to 60°C Storage Temperature – −25°C to 75°C Humidity – 35–95% RH Temperature Drift – <10% detection distance variation within operating range Dimensions – 75 mm × 18 mm (Ø) Key Features Adjustable Threshold – Rear screw adjusts detection distance Gravity Interface – Plug-and-play with Arduino and IO expansion shields Simple Digital Output – No analogue reading or complex code required Compact Cylindrical Design – Screw-mount holes for easy installation Ideal For Robot wall detection and wall following Obstacle avoidance in robotics Proximity trigger systems Interactive media installations Note: Infrared sensors can be affected by direct sunlight and reflective surfaces. Best suited for indoor use. Package Contents 1× Gravity Digital Adjustable IR Proximity Sensor Resources Wiki Documentation (DFRobot)
