Sintra Air on DSM501a - Arduino

 Hello comunity, I'm new here.

Have been able to post DHT readings to my channel with no problems at all.

Recently, I've been trying, with no any success to post data from a dust sensor, the DSM501a.

So, I can read the sensor on Arduino serial, but once I try to implement it on the sketch that I'm using to upload DHT sensor, this part of the code seems to stop everything 🙁

void setup ()

// Initialize DSM501
dsm501.begin(MIN_WIN_SPAN);

// wait 60s for DSM501 to warm up
for (int i = 1; i <= 60; i++)
{
delay(1000); // 1s
Serial.print(i);
Serial.println(" s (wait 60s for DSM501 to warm up)");
}

Any ideas?
