What is IR?
An IR sensor is an electronic device that emits infrared light to detect objects and their surroundings. It consists of infrared emitting and receiving components. The emitting tubes emit infrared light, which reflects off objects and is detected by the receiving tube. This reflection triggers a signal processing circuit, resulting in a digital output signal when an obstacle (reflective surface) is detected. The sensor has an adjustable detection range of 2 to 30 centimeters using a potentiometer and is used for proximity sensing and obstacle detection in various applications.
Circuit:
Code:
int IR = 2;
int led = 13;
void setup() {
pinMode(led, OUTPUT);
pinMode(IR, INPUT);
Serial.begin(9600);
}
void loop() {
int SensorValue = digitalRead(IR);
Serial.print("IR Value: ");
Serial.println(SensorValue);
delay(1000);
if (SensorValue==LOW){ // low means object detected
digitalWrite(led, HIGH);
}
else
{
digitalWrite(led, LOW);
}
}
