The Waveshare Infrared Proximity Sensor is a compact, reliable obstacle-avoidance module designed for use with Arduino, Raspberry Pi, and other microcontrollers. It employs an infrared transmitter and receiver pair to detect obstacles in its path. This non-contact sensor can detect objects at close range (typically 2–30 cm) and outputs a digital signal to indicate the presence of an object. It is widely used in robotics, line-following cars, automated systems, and proximity alert projects.
It features a potentiometer to adjust detection range and onboard indicators for power and detection status, making it easy to debug and calibrate.
Key Features:
• Infrared obstacle detection using IR transmitter & receiver
• Adjustable sensing distance (2 cm – 30 cm)
• Digital output signal (HIGH/LOW)
• Onboard detection and power LEDs
• Compatible with 3.3V or 5V logic levels
• Easy interfacing with microcontrollers and development boards
• Compact size, easy mounting via screw holes
