Sensor de distancia SHARP

Sensor de distancia SHARP 2y0a21

Este sensor óptico tiene un rango de 10-80cm (aunque modelos similares tienen otros rangos).

Es importante saber que SHARP devuelve la distancia en valores analógicos, por tanto es importante que el pin de datos esté conectado a un pin analógico. En el caso de NodeMCU sólo existe un pin analógico: A0.

 * getDistance
 *
 * Example of using SharpIR library to calculate the distance beetween the sensor and an obstacle

 * -----------------------------------------------------------------------------------
 *
 * Things that you need:
 * - Arduino
 * - A Sharp IR Sensor
 *
 *
 * The circuit:
 * - Arduino 5V -> Sensor's pin 1 (Vcc)
 * - Arduino GND -> Sensor's pin 2 (GND)
 * - Arduino pin A0 -> Sensor's pin 3 (Output)
 *
 *
 * See the Sharp sensor datasheet for the pin reference, the pin configuration is the same for all models.
 * There is the datasheet for the model GP2Y0A41SK0F:

//GP2YA41SK0F
//GP2Y0A21YK0F
//GP2Y0A02YK0F


//Create a new instance of the library
//Call the sensor "sensor"
//The model of the sensor is "GP2Y0A21YK0F"
//The sensor output pin is attached to the pin A0
SharpIR sensor( SharpIR::GP2Y0A21YK0F, A0 );

void setup()
{
  Serial.begin( 9600 ); //Enable the serial comunication
}

void loop()
{
  int distance = sensor.getDistance(); //Calculate the distance in centimeters and store the value in a variable

  Serial.println( distance ); //Print the value to the serial monitor
}
