Description

Transmitter and receiver in one photoelectric sensor. The sensor has an adjustable detection distance and visible light interference. The range is from 3cm to 80cm and can adjusted via an integrated potentiometer. It is easy to use and is ideal for panel mounting.

Specifications:

• Input voltage: +5V DC
• Current consumption: > 25mA (min) ~ 100mA (max)
• Dimension: 1.7cm (diameter) x 4.5cm (length)
• Cable length: 45cm
• Detection of objects: transparent or opaque
• Diffuse reflective type
• Sensing range: 3cm to 80cm (depends on obstacle surface)
• NPN output (normally high)
• Environment temperature: -25 °C ~ 55 °C

Pin Configuration:

• Brown Wire: +5V
• Blue Wire: GND
• Black Wire: DIGITAL OUTPUT – Open collector pull down (Use 10K pull up resistor to +5V)

More Information:

• Infrared Distance Sensor Type E18-D80NK

 

Example Code – Pin 5 used as signal input:

void setup() 
  {
    Serial.begin(9600); //Start serial communication boud rate at 9600
    pinMode(5,INPUT); //Pin 5 as signal input
  }

void loop()  
{
 while(1)

  {
   delay(500);
   if(digitalRead(5)==LOW)  { 
    // If no signal print collision detected
     Serial.println("Collision Detected.");
   }
   else 
  {
     // If signal detected print collision detected
     Serial.println("No Collision Detected.");
  }
 }
}
