Photoelectric beam sensors are fascinating devices that can revolutionize your Arduino projects. In this blog post, we dive deep into the world of photoelectric beam sensors and explore how they work with Arduino.

Understanding the Basics

Photoelectric beam sensors detect the presence or absence of an object by using a beam of light. When the beam is interrupted, the sensor triggers a response, making them ideal for various applications such as security systems, automation, and obstacle detection.

Setting Up the Sensor

To use a photoelectric beam sensor with Arduino, you need to connect it to the appropriate pins on the microcontroller. Once connected, you can start coding to read the sensor's output and take actions based on the readings.

Sample Code

#define sensorPin 2
int sensorState = 0;
void setup() {
 pinMode(sensorPin, INPUT);
}
void loop() {
 sensorState = digitalRead(sensorPin);
 if (sensorState == HIGH) {
 // Object detected
 } else {
 // Object not detected
 }

Applications of Photoelectric Beam Sensors

Photoelectric beam sensors have a wide range of applications. They are commonly used in automated doors, parking systems, and even in industrial settings for precise object detection.
