ESP32 sharp dust sensor and wifi?

Hello Everyone!

I've been struggling for days trying to get both work together however, I've seen online when WIFI is in use only pins 32-36 become available? is this true?

Code: Select all

#include <GP2Y1010AU0F.h>

int measurePin = 26;   // Connect dust sensor analog measure pin to esp32 26 pin
int ledPin     = 27;    // Connect dust sensor LED pin to esp32 pin 27

GP2Y1010AU0F dustSensor(ledPin, measurePin); // Construct dust sensor global object
float dustDensity = 0;

void setup() {
  Serial.begin(115200);
  Serial.println(F("GP2Y1010AU0F Dust Sensor Library Example"));

  dustSensor.begin();
}

void loop() {
  dustDensity = dustSensor.read();
  
  Serial.print("Dust Density = ");
  Serial.print(dustDensity);
  Serial.println(" ug/m3");

  delay(5000);
}

Yes, only 32-39 can be used as analog pins with WiFi.

Yes, only 32-39 can be used as analog pins with WiFi.

But the dust sensor only works with pins 26/27
