Well - get rid of the delay(1000); // ATRASO EM MILI SEGUNDOS PRA ESTABILIDADE in your loop and things will go faster...

Also check the missing {} for the if the temp is in between min and max... that’s probably an issue

Should look like this

if (condition) {
   Instruction1;
   Instruction2;
   Instruction3;
}

if you do

if (condition) 
   Instruction1;
Instruction2;
Instruction3;

then only instruction1 is conditional, Instruction2 and Instruction3 will always get executed (regardless of indentation)
