Sensor Data is full when scripts combined?

Hello, I'm facing a strange error when i combine my scripts which both work absolutely fine individually when joined my sensor data is maxed out.

Dust Sensor on its own (correct)

I've broke this down and it seems to break as soon as i add this

 WiFi.begin(ssid, password);
  Serial.println("Connecting");
  while(WiFi.status() != WL_CONNECTED) { 
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.print("Connected to WiFi network with IP Address: ");
  Serial.println(WiFi.localIP());

Any ideas would be grateful!

tried a completely different way...

same result...

Dust Density = 3299.17 ug/m3
HTTP Response code: 500
httpRequestData: dustDensity=
Dust Density = 3299.17 ug/m3
HTTP Response code: 500
httpRequestData: dustDensity=
Dust Density = 3299.17 ug/m3
HTTP Response code: 500
httpRequestData: dustDensity=
Dust Density = 3299.17 ug/m3
HTTP Response code: 500
httpRequestData: dustDensity=
Dust Density = 3299.17 ug/m3
HTTP Response code: 500

The 500 response code was expected, it's the 3299.17 ug/m3 that's the problem.

It's like no matter what dust sensor script/library i use which all work fine on their own once the networking and sending it to my website comes into play it just breaks...

Do you have a pin conflict? Can you run the dust sensor on different pins?
