Infrared Obstacle Avoidance IR Sensor Module

Infrared Obstacle Avoidance IR Sensor Module

The Infrared Obstacle Avoidance IR Sensor Module is a sensor module designed to detect obstacles and avoid a collision. It uses infrared (IR) technology to detect the presence of obstacles and provides a digital output to indicate the presence or absence of an obstacle. The detection range is from 2cm to 30cm, and it can be adjusted by a built-in potentiometer. The module has three pins: GND pin, VCC pin, and OUT pin.

• Datasheet
• User Manual

Here’s how it works:

1. An infrared obstacle sensor module has a built-in IR transmitter and IR receiver.
2. The IR transmitter emits the IR signal.
3. The IR receiver looks for the reflected IR signal to determine if the object is present or not.
4. The presence of obstacle is reflected in the OUT pin:
   • If the obstacle is present in front of the sensor, the sensor’s OUT pin is LOW.
   • If the obstacle is NOT present in front of the sensor, the sensor’s OUT pin is HIGH.

How to Integrate into Projects:

Empower yourself with the knowledge of integrating the Infrared Obstacle Avoidance IR Sensor Module into your robotic projects.

1. Installation:
   • Connect the sensor module to the power supply within the specified voltage range.
   • Place the module in a strategic position on your robot to ensure optimal obstacle detection.
2. Adjustment of Detection Range:
   • Use the adjustable potentiometer to set the desired detection range according to your project requirements.
3. Connectivity:
   • Interface the digital output signal of the module with your robot’s control system.
   • Leverage the indicator LED to visually confirm obstacle detection.
4. Integration into Robotics Projects:
   • Seamlessly integrate the sensor module into your robotics projects, such as obstacle-avoiding robots, automated guided vehicles (AGVs), and more.

int irSensorPin = 2; // Define the input pin for the IR sensor

int ledPin = 13; // Define the output pin for the LED

void setup() {

  pinMode(irSensorPin, INPUT); // Set the IR sensor pin as input

  pinMode(ledPin, OUTPUT); // Set the LED pin as output

}

void loop() {

  int irSensorValue = digitalRead(irSensorPin); // Read the value of the IR sensor

  if (irSensorValue == LOW) { // If the obstacle is present

    digitalWrite(ledPin, HIGH); // Turn on the LED

  } else { // If the obstacle is NOT present

    digitalWrite(ledPin, LOW); // Turn off the LED
