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.

Jargon buster
Plain-language definitions for the technical terms used above.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- Proximity sensor
- A sensor that detects the presence of a nearby object without physical contact, using methods such as infrared, ultrasonic, capacitive, inductive or time-of-flight. Useful ranges vary widely between types, from a few millimetres to several metres, so check a given sensor's specified range to see whether it suits close-up touch-free triggers or longer-distance detection.
