Crowtail- Adjustable Infrared Sensor

Introduction


This infrared distance switch features a high-sensitivity photoreflector to perform distance detection function,ranging from 3cm to 50cm. When the infrared light emitted by the emitter gets reflected on a surface that blocked it, the phototransistor can pick up the signal for distance calculation. Also a potentiometer for adjustment is arranged for easy and clear use. It is small, easy to use/assemble, and inexpensive. Useful for robotics, interactive media, industrial assembly line, etc.
Model: CT0036AIS

Usage


Hardware

Connect this sensor to your Arduino/Crowduino digital pins( D2 for example). When there is an object behind this sensor, the output would be low.

Programming

1.Download the following program to Arduino, Please refer to here

void setup()  {
 Serial.begin(9600);
 pinMode(2,INPUT);
}
void loop()  {
 while(1)  {
   delay(500);
   if(digitalRead(2)==LOW)  {
     Serial.println("object detected.");
   }
   else  {
     Serial.println("no object detected.");
   }
 }
}

2.open the serial monitor , and set the baudrate to 9600, you will see the output changes with the object behind this sensor or not.
