A compact digital infrared distance sensor from DFRobot's Gravity range, designed for edge detection and close-range proximity sensing. It detects objects within 1–10 cm and outputs a simple digital HIGH/LOW signal — perfect for preventing robots from falling off tables or down stairs.
Connects directly to an Arduino digital pin using the included Gravity sensor cable. The low power consumption (under 10 mA) and lightweight design (under 5 g) make it ideal for mobile robotics platforms.
Key Features
- 1–10 cm Detection Range – Close-range infrared proximity sensing

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- 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.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
