Description

Transmitter launch a certain frequency infrared, when meet obstacle in the detection direction, the infrared receiver is reflected back by the receiver tube, after processing through the comparator circuit, the green indicator light will illuminate while the signal output interface output digital signal (a low-level signal) can be adjusted via potentiometer.

Specifications:

  • The module detects the distance 2 ~ 30cm, detection angle 35 °,
  • The sensor module output port OUT can be directly connected with the microcontroller
  • IO port can also be driven directly to a 5V relay
  • It uses a stable comparator which is LM393
  • The module is supplied with 3-5V DC power
  • OUT : digital output interfaces (0 and 1);

Getting started with the Obstacle Infrared Sensor module

The device consists of an Infrared Transmitter, an Infrared Detector, and support circuitry.  It only requires three connections. When it detects an obstacle within range it will send an output low.

Hardware required

Obstacle Infrared Sensor module Pin Outs

Connecting the Hardware

Use the picture below.  It only requires three wires.

Copy, Paste and Upload the Sample Sketch

// IR Obstacle 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 OBSTACLE

void setup() {
pinMode(LED, OUTPUT);
pinMode(isObstaclePin, INPUT);
Serial.begin(9600);
}

void loop() {
isObstacle = digitalRead(isObstaclePin);
if (isObstacle == LOW){
Serial.println("OBSTACLE!!, OBSTACLE!!");
digitalWrite(LED, HIGH);
}
else{
Serial.println("clear");
digitalWrite(LED, LOW);
}
delay(200);
}

Test the Tutorial Sketch

Move your hand towards the Obstacle Infrared Sensor module . Open your serial monitor and vary the distance of your hand while viewing the serial monitor.   The output should look like the picture below:
