Tutorial: How to use AD-032 IR Sensor Module

The AD-032 IR sensor is ideal for projects that require obstacle detection. Useful for beginners and intermediate makers.

What you need

• Arduino or compatible
• Power cable
• 10kΩ resistor

Steps

1. 1. Connect the module to the Arduino using the following pins: VCC to 5V, GND to GND, OUT to a digital pin.
2. 2. Attach the 10kΩ resistor between the VCC pin and the OUT pin.
3. 3. Upload the following sketch to the Arduino.
4. 4. Adjust the detection range by tuning the potentiometer on the module.
5. 5. Test the sensor by placing an object in front of the module.
6. 6. Check the datasheet for the detection frequency.
7. 7. Adjust the detection frequency with the potentiometer.
8. 8. Connect the signal to your project.

Example code

```cpp
#include <Arduino.h>

int sensorPin = 2;
int sensorValue = 0;

void setup() {
  Serial.begin(9600);
  pinMode(sensorPin, INPUT);
}

void loop() {
  sensorValue = digitalRead(sensorPin);
  Serial.println(sensorValue);
  delay(100);
}
```

Mini project

Build a simple robot that stops when it encounters an obstacle.

Common mistakes

• Incorrectly adjust the potentiometer.
• Connect the VCC to 3.3V instead of 5V.
• Omit the 10kΩ resistor.
• Fail to check the detection frequency.

Recommended accessories

• Arduino Uno
• Potentiometer
• 10kΩ resistor
• Power cable
