DFROBOT Gravity Digital Adjustable IR Distance Sensor
DFROBOT Gravity adjustable IR proximity sensor with 3-80cm range. Perfect for Arduino robotics, IoT & prototyping. Plug-and-play 3-pin interface.
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.
