QB050 Photoelectric Sensor

1。Product Introduction

Photoelectric sensor are commonly used to detect the presence, position, or motion of an object.

It consists of a transmitter, which generates an infrared beam, and a receiver, which receives the infrared beam. When the middle is blocked, the receiver cannot receive the light signal, so as to detect the presence or movement of the object.

2.Parameter Specification

Parameter	Value//Description
Operating voltage	3.3V~5V
Operating temperature	-10°C~+50°C
Output signal	Digital signal
Size	3.16cm*2.38cm

3.Wiring Diagram

PIR Motion Sensor	UNO
VCC	5V
GND	GND
S	Digital Pin 7

4.Sample Code

//www.acebott.com
void setup() {
pinMode(7,INPUT);//Set pin 7 to input mode
Serial.begin(9600);//Set baud rate to 9600
}
void loop() {
Serial.println(digitalRead(7));//Read the state of pin 7and print it to the serial monitor
delay(1000); 
}

5.Test Result

After uploading the code to the controller board, open the serial port monitor of the Arduino IDE and set the baud rate to 9600.

When there is no object blocking the sensor, the sensor returns data 0. When there is an object blocking, the sensor returns data 1.
