Which sensor monitors heat?

Lately Ive been noticing that wenever its hot(humid) my idle seems a little rough, sometimes goes way down during stops to as low as 570rpm. I was wondrin if i can trick a sensor (where to find it??) so i would have such probs anymore. Thanx!!

I believe our cars have a CTS(coolant temp sensor) that tells the ECU to adjust the TPS(throttle position sensor) and idle based off of the coolant temp. If the coolant temp is cold, then the TPS will raise the idle until the coolant temp rises. How you would trick it I dunno. Also you could have a bad TPS. Read this post here:
