I noticed something very strange around the time it takes to send the requesttemperature command reading and when i made one small change the ds18b20 sped up considerably. The sensor has only three contacts, as you can see in the following figure. You will be able to connect multiple temperature sensors ds18b20. I would like to know what is in the dallastemperature that conflicts with radiohead making the code to hang.
To begin, we need to include both of the onewire and the dallastemperature headers so we can use these within the code. The system starts and shows the temperature, if the temperature reaches 25 degrees, then the green led is activated and the room starts to cool until the temperature drops to 23 degrees, the air conditioner turns off red led until the temperature rises again.
