Features

• Adjustable to fit different project requirements
• High sensitivity to detect obstacles accurately

What it is for

Obstacle avoidance infrared sensor modules are ideal for creating obstacle-avoiding robots using two DC motors. The module is compatible with Arduino and can be integrated into various prototypes that require distance detection.

Tutorial: How to use Obstacle Avoidance Infrared Sensor Module

The obstacle avoidance infrared sensor module is a useful device for robotics projects and prototypes that require distance detection. It is ideal for beginners and intermediates who want to create devices capable of interacting with the surrounding environment.

What you need

• Arduino Uno or compatible
• USB A-MicroB cable
• Connection to PC

Steps

1. Connect the following pins of the obstacle avoidance module to those of the Arduino: VCC to 5V, GND to GND, OUT to a digital switch (for example D2).
2. Open Arduino IDE and create a new folder for the project.
3. Include the ‘Wire.h’ library. If it is not present, download and install the ‘Adafruit_Sensor’ library from online libraries.
4. Write the following sketch, modifying the connection pins if necessary.
5. Compile and run the code on your Arduino. Check that the serial monitor output correctly indicates the presence or absence of obstacles.
6. Calibrate the sensor to fit your specific needs by checking the instructions provided with the product.
7. Try integrating this module into a larger project, such as an obstacle-avoiding robot or a home security system.
8. Explore additional features of the sensor by reading the official documentation and datasheet.

Example code

void setup() {
  Serial.begin(9600);
}

void loop() {
  int val = digitalRead(pin); // Verifica sul datasheet per il pin corretto.
  if(val == HIGH) {
    Serial.println("Ostacolo rilevato");
  } else {
    Serial.println("Nessun ostacolo");
  }
}

Mini project

Create an obstacle-avoiding robot using this infrared sensor and two DC motors. Set the module to detect obstacles at a distance of 10-20 cm.

Common mistakes

• The OUT signal does not change when there are nearby obstacles.
• The sensor does not respond correctly to changes in configuration.
• USB connection issues between Arduino and PC.
• Compilation error due to missing necessary libraries.

Recommended accessories
