Sensor Debu Sharp GP2Y1010

Ide rangkaian (sumber: Application note of Sharp dust sensor GP2Y1010AU0 :

Berikut ini contoh software ESP32 untuk membaca data dari sensor

Konfigurasi:

• input analog: pin 34
• output untuk kendali LED: pin 23

#define LED_SENSOR 23
#define ADC_INPUT 34
int sensorValue = 0;        // value read from the pot
int outputValue = 0;        // value output to the PWM (analog out)

void setup() {
  // initialize serial communications at 9600 bps:
  Serial.begin(115200);
  pinMode(LED_SENSOR, OUTPUT);
}

void loop() {
  // read the analog in value:
  digitalWrite(LED_SENSOR, HIGH);
  delayMicroseconds(280); 
  sensorValue = analogRead(ADC_INPUT); // measurement 280 us after signal start
  delayMicroseconds(40); // total signal duration 320 us
  digitalWrite(LED_SENSOR, LOW); // turn off LED

  // print the results to the Serial Monitor:
  Serial.print("sensor = ");
  Serial.println(sensorValue);
  delay(1000);
}
