2B18 Distance Measuring Sensor Infrared Proximity Sensor - Sharp GP2Y0A02YK0F

GP2Y0A02YK0F is a distance measuring sensor unit, composed of an integrated combination of PSD (position sensitive detector) , IRED (infrared emitting diode) and signal processing circuit. The variety of the reflectivity of the object, the environmental temperature and the operating duration are not influenced easily to the distance detection because of adopting the triangulation method. This device outputs the voltage corresponding to the detection distance. So this sensor can also be used as a proximity sensor.

Features:

• Distance measuring range : 20 to 150 cm
• Analog output type
• Package size : 29.5×13×21.6 mm
• Consumption current : Typ. 33 mA
• Supply voltage : 4.5 to 5.5 V

Specification:

• Supply voltage: 4.5 to 5.5 V

Code:

#define sensor A0 // Sharp IR GP2Y0A41SK0F (4-30cm, analog)

void setup() {
  Serial.begin(9600); // start the serial port
}

void loop() {
  
  // 5v
  float volts = analogRead(sensor)*0.0048828125;  // value from sensor * (5/1024)
  int distance = 13*pow(volts, -1); // worked out from datasheet graph
  delay(1000); // slow down serial port 
  
  if (distance <= 30){
    Serial.println(distance);   // print the distance
  }
}
