Infrared Obstacle Avoidance IR Sensor Module

An Infrared (IR) Sensor is an electronic device that uses infrared light to detect objects or measure distances. IR sensors are commonly used in various applications, such as proximity detection, motion sensing, and communication with devices like TVs or robots.

 

Technical Specifications:

• Operating Voltage Range: 3.6~5 VDC
  
• Average Current Consumption (mA): 0.06mA
  
• Field of view: 35°
  
• Distance Measuring Range: 2 ~ 30cm

Pinouts:

Connection with Arduino:

Module	Arduino UNO
VCC	5V
GND	GND
OUT	Pin 7

 

Sample code:

const int sensorPin = 7; // IR sensor output pin

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

void loop() {
    int sensorValue = digitalRead(sensorPin);

    if (sensorValue == LOW) { // Object detected
        Serial.println("Object detected!");
    } else {
        Serial.println("No object detected.");
    }

    delay(200); // Short delay for stability
}
