DFROBOT Gravity Digital Adjustable IR Distance Sensor

The DFROBOT Gravity Digital Adjustable IR Distance Sensor is a versatile and user-friendly infrared proximity sensor, perfect for rapid prototyping and a wide range of electronic projects. Its adjustable detection range of 3 to 80cm makes it suitable for numerous applications, from robotics to smart home automation. The sensor operates on a 5V power supply and draws a modest 100mA current, ensuring compatibility with common microcontroller boards.

Designed for ease of use, it features a plug-and-play 3-pin Gravity interface, simplifying connections and reducing wiring errors. The colour-coded wires are clearly indicated: Red for +5V, Yellow for the signal output, and Green for Ground (GND). Its compact, round shape and integrated screwable mounting holders allow for flexible and secure installation. You can easily mount it in a drilled hole of matching diameter on a custom robot chassis and adjust its aiming angle for optimal performance.

Ideal Applications

This sensor excels in robotics, serving as a reliable solution for wall detection, obstacle avoidance, and creating wall-following robot behaviours. It can also function as a versatile trigger system for interactive projects. Beyond robotics, it's perfect for embedded system design, IoT (Internet of Things) development, and hobbyist electronics education. A creative application includes placing it near a PC to automatically turn a monitor on or off based on presence detection.

Key Features & Considerations

• Adjustable Range: Fine-tune the detection distance from 3cm to 80cm to suit your specific project needs.
• Easy Integration: The standard Gravity 3-pin connector allows for instant connection to compatible DFROBOT shields and expansion boards, streamlining the development process.
• Flexible Mounting: The screwable holders enable secure fixation and positional adjustment on homemade robots or enclosures.
