Infrared Obstacle Avoidance Sensor Module

This Infrared Obstacle Avoidance Sensors Module has a built-in IR transmitter 5mmLED and IR receiver 5mmLED that sends out IR waves and then looks for the reflected IR waves to detect the presence of any objects in front of the sensor module. The module has an on board potentiometer that let users adjust the detection range. This sensor  can be used in light and complete darkness.

Infrared Obstacle Avoidance Sensors Module Features

  • There is an obstacle, the green indicator light on the circuit board
  • Detection distance: 2 ~ 30cm
  • Detection angle: 35 °
  • Comparator chip: LM393
  • 3mm screw holes for easy mounting
  • 35x15x14mm

Arduino code

EXAMPLE CODE: // IR Collision Detection Module // Henry's Bench
int LED = 13; // Use the onboard Uno LED
int isObstaclePin = 7; // This is our input pin
int isObstacle = HIGH; // HIGH MEANS NO Object In Front Of Sensor

void setup() {
pinMode(LED, OUTPUT);
pinMode(isObstaclePin, INPUT);

void loop() {
isObstacle = digitalRead(isObstaclePin);
if (isObstacle == LOW) {
Serial.println("OBSTACLE!!, DETECTED!!");
digitalWrite(LED, HIGH);

else {
digitalWrite(LED, LOW);
