Waveshare Infrared Reflective Sensor Module - Digital/Analog Output
The Waveshare Infrared Reflective Sensor Module is a versatile 3.3V/5V-compatible optical sensor featuring both digital and analog outputs, ideal for Arduino, Raspberry Pi, and robotics projects. It provides non-contact detection of objects and surface reflectivity within a 0-30 mm range.
Features
- Dual digital and analog output signals for flexible system integration.
- Wide operating voltage range from 3.0V to 5.3V for compatibility with 3.3V and 5V logic systems.
- Adjustable detection sensitivity via on-board potentiometer.
- Compact design with a 35° viewing angle and integrated IR LED for precise reflective sensing.
- Includes a wide-range voltage comparator (LM393) for stable signal conditioning.

This module integrates an infrared transmitter (IR LED) and receiver (phototransistor) to perform reflective object detection. The IR LED emits light at a typical wavelength of 830-950nm, which reflects off surfaces and is captured by the receiver. The intensity of the reflected signal is conditioned by the onboard LM393 comparator, providing a clean digital output, while the raw analog signal is also accessible for precise reflectivity measurement.
Designed for indoor use to avoid interference from ambient sunlight, the sensor is commonly employed in robotics for line tracking and obstacle avoidance. Its compact PCB includes a 3mm mounting hole for easy installation. The detection range is influenced by the color and reflectivity of the target surface, with white objects providing the maximum range of up to 30 cm.
