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.\n\nFeatures 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.\n\nSpecifications\n\n\nDetection Range – 0–200 cm (adjustable)\n\nSignal Type – Digital (PNP normally open)\n\nOutput – LOW = no obstacle, HIGH = obstacle detected\n\nOperating Voltage – 3–5 V\n\nInterface – Gravity XH2.54 3-pin\n\nOperating Temperature – −15°C to 60°C\n\nStorage Temperature – −25°C to 75°C\n\nHumidity – 35–95% RH\n\nTemperature Drift – <10% detection distance variation within operating range\n\nDimensions – 75 mm × 18 mm (Ø)\n\n\nKey Features\n\n\nAdjustable Threshold – Rear screw adjusts detection distance\n\nGravity Interface – Plug-and-play with Arduino and IO expansion shields\n\nSimple Digital Output – No analogue reading or complex code required\n\nCompact Cylindrical Design – Screw-mount holes for easy installation\n\n\nIdeal For\n\nRobot wall detection and wall following\nObstacle avoidance in robotics\nProximity trigger systems\nInteractive media installations\n\n\n\nNote: Infrared sensors can be affected by direct sunlight and reflective surfaces.
