Adjustable_Infrared_Sensor_Switch__SKU_SEN0019_-DFRobot

Introduction

The DFRobot Digital Adjustable Infrared Proximity Sensor is a set of a transmitter and a receiver in one photoelectric switch sensor. The detection distance can be adjusted according to the users specfic demands. The sensor 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 scenarios. The switching signal output differs in accordance to the obstacles that it detects. 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
• Recommended Operating Distance: 10~80cm
• Minimum Operating Distance: 3cm
  (when the detected surface is non-reflective black plane)
• Maximum Operating Distance: 90cm
  (when the detected surface is flat reflective white plane)
• Pin description:
  • Brown - 5V
  • Blue - GND
  • Black- Signal
• Digital output:
  • "0" - found barrier (~0V)
  • "1" - no barrier (~4V)
• Dimension: 45x18mm

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:");
  Serial.println(digitalRead(InfraredSensorPin),BIN);
  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.
