Waveshare IR Reflective Sensor Module - Digital/Analog Output, 3-5.3V
The Waveshare IR Reflective Sensor Module is a versatile infrared proximity sensor compatible with 3.3V and 5V microcontrollers like Arduino, Raspberry Pi, and ESP32. It provides both digital and analog outputs for detecting obstacles 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 3.3V/5V logic compatibility.
- Adjustable detection sensitivity via onboard potentiometer.
- Compact PCB design with 2.0mm mounting holes for easy installation.
- Features a wide-range LM393 comparator for stable signal conditioning.

This module integrates an infrared transmitter (IR LED) and receiver (phototransistor) to perform reflective sensing. The transmitter emits infrared light at a center wavelength of 830-950nm, which reflects off surfaces back to the receiver. The intensity of the received signal, converted to an electrical current, determines the presence or proximity of an object, with detection range influenced by surface color and reflectivity.
The onboard LM393 voltage comparator provides a clean digital output signal, while the analog output allows for precise reflectance measurement. The module is designed for indoor use to avoid interference from direct sunlight and features a 35° viewing angle for focused detection. Its compact form factor and standard 4-pin interface make it suitable for integration into robotics, automation, and line-following applications.
