Introduction

The DFRobot Adjustable Infrared Sensor Switch is a set of transmitter and receiver in one of the photoelectric switch sensor. The detection distance can be adjusted according to the demand. The DFRobot Adjustable Infrared Sensor Switch is small, easy to use, inexpensive, easy to assemble and can be widely used in robot to avoid obstacles, interactive media, industrial assembly line, and many other occasions. The switching signal output differs in accordance to the obstacles. It remains high when no obstacles and remains low when there are obstacles. There is also a red led on its back to indicate the sensor status.

Specification
• Power supply 5V
• Working Current <100mA
• Adjustable detection range 3cm - 80cm
• Pin description:

Red - 5V Green - GND Yellow - Digital output
• Digital output "0" - found barrier ~0V "1" - no barrier ~4V
• Dimension 45x18mm

Tutorial

Connection Diagram

Sample Code
const int InfraredSensorPin = 4;//Connect the signal pin to the digital pin 4 const int LedDisp = 13;
void setup

Serial.begin 57600 Serial.println "Start!" pinMode InfraredSensorPin,INPUT pinMode LedDisp,OUTPUT digitalWrite LedDisp,LOW ;
void loop
if digitalRead InfraredSensorPin == LOW digitalWrite LedDisp,HIGH else digitalWrite LedDisp,LOW Serial.print "Infrared Switch Status:" delay 50 ;

Result

Cover the sensor head with your hand, the LED Pin13 on board will light up, hold it toward an open area, the LED will be off. Open Arduino IDE serial monitor, you can also get the Infrared sensor status.

Trouble shooting

Q We have to use manual, because describes explanation is too simple? A This is a photoelectric switch, only three lines, power, ground and output, so have not too complicated presentation.

Q Why Connect the power, light has been lit? A To ensure stable power supply is 5V ± 2%, followed by the output of the probe is not connected to the microcontroller output port.

Q If need the pull-up resistor, how much should be? A About 10K. Any question and more cool ideas to share, please visit DFRobot Forum
