DHT11 Sensore Temperatura e Umidità per comando relè

[robtillaart]

PLease use English (too) on the international section.

Hello everyone, I'm new to the forum, I offer you the attention my problem: I have a DHT sensor 11 to detect the temperature and humidity environment, which I have to control two relays and the first relay must be precisely controlled to overcome in a specific temperature, while the second relay is to be commanded to the overcoming of a certain humidity.
The sensor is working properly in the sense that I show on the serial monitor both the values ??of temperature and humidity, only that I can not set the thresholds for temperature and humidity to which must be controlled relays, or rather the system does not recognize me values inserted in the sketch, with the if statement.

First please modify your post and use code tags around your code ==> # button above the smileys.

if(Serial.available()); <<<<<<<<<< ; may not be there

if(DHT11.temperature,1 > 27); <<<<<<<<<< ; may not be there

if(DHT11.temperature,1 > 27); The ,1 is part of a print statement you copied and paste. It is not correct C

Try this construct

if (DHT11.temperature > 27)
{
        digitalWrite(2,HIGH);
}
if (DHT11.temperature < 26)  // use a different level to prevent continuous ON/OFF cycles of the relays.
{
        digitalWrite(2, LOW);
}
