Try this 4 dec digits

// Send Events to the Web Server with the Sensor Readings
events.send(“ping”,NULL,millis());

char buffer[80];

// events.send(String(pres).c_str(),”pressure”,millis());
sprintf(buffer, “%.4f”, pres);
events.send(String(buffer).c_str(),”pressure”,millis());

//events.send(String(alt).c_str(),”altitude”,millis());
sprintf(buffer, “%.4f”, alt);
events.send(String(buffer).c_str(),”altitude”,millis());

//events.send(String(temp).c_str(),”temperature”,millis());
sprintf(buffer, “%.4f”, temp);
events.send(String(buffer).c_str(),”temperature”,millis());

Thank you for the helpfull instruction!

With the instruction from DFRobot it does not work.

I translate from Portuguese to English by google translator.
Hello, I set up your project and it worked, but I would like to leave it with a house after the comma, which field changes?

the codes below where it was 2f I changed it to 1f, but it only changed on the serial monitor, it didn’t change on the cell phone screen. I couldn’t find where it changes on the cell phone screen.
Serial.printf(“Pressure = %.2f hPa \n”, pres);
Serial.printf(“Altitude = %.1f m \n”, alt);
Serial.printf(“Temperature = %.1f ºC \n”, temp);

Obrigada 🙂

Yes!

Thank you 🙂
