Connection Diagram

Sample Code 

const int sensorPin = 3;     // the number of the sensor pin
const int ledPin =  13;      // the number of the LED pin
int sensorState = 0;         // variable for reading the sensor status
void setup() {
  pinMode(ledPin, OUTPUT);      
  pinMode(sensorPin, INPUT); }
void loop(){
  // read the state of the sensor value:
  sensorState = digitalRead(sensorPin);
  // if it is, the sensorState is HIGH:
  if (sensorState == HIGH) {     
     digitalWrite(ledPin, HIGH);  
  } 
  else {
       digitalWrite(ledPin, LOW); 
  }
}

Result

Done uploading the code to board, you can see the led on both UNO board and obstacle detector sensor is turned on.
If we put a foam block in front of the sensor, this time when sensor detects the obstacle, sled on the sensor will be turned on.

Conclusion

The keyestudio Infrared Obstacle Avoidance Sensor is a versatile and reliable tool for any robotics enthusiast or developer. With its precise functionality and adjustable parameters, it enables robots to navigate effectively while avoiding obstacles. Investing in this sensor enhances your robotic projects, ensuring safe and effective operation in various environments.
