Generic Infrared Obstacle Avoidance Sensor Module (Active Low) - LM393 Comparator, 2-30cm Range
This active-low infrared obstacle avoidance sensor module integrates an IR transmitter/receiver pair with an LM393 comparator for reliable digital output. It is compatible with 3.3V and 5V microcontroller systems like Arduino, Raspberry Pi, and ESP32, providing a simple interface for proximity detection and collision avoidance applications.
Features
- Digital output switches to active-low logic upon obstacle detection.
- Adjustable detection range from 2 cm to 30 cm via onboard potentiometer.
- Wide operating voltage range of 3.3V to 5V DC for flexible system integration.
- Features a 35° detection cone for focused proximity sensing.
- Onboard LM393 comparator ensures stable signal conditioning and a clear detection indicator LED.

This module operates on the principle of infrared reflectance. The integrated IR LED emits a beam of infrared light. When an object enters the sensor’s detection cone, the light reflects back to the phototransistor receiver. The onboard LM393 voltage comparator processes this signal, driving the digital output pin low when the reflected intensity exceeds a user-adjustable threshold set by the potentiometer.
Designed for easy integration, the module provides a simple three-wire interface (VCC, GND, OUTPUT) and includes 3mm mounting holes for secure installation. Its low average current consumption makes it suitable for battery-powered projects and robotics platforms requiring reliable obstacle avoidance.
