So I'm using a temperature sensor to detect the air temperature in a box. I'm getting readings of about 225°C. Thinking that's weird I check the algorithm converting the input to celceius. Seems legit. Okay must be hardware, let's try resetting the sensor into the board. Turns out the readings weren't lying... Long story short, if you reverse the polarity of a temperature sensor you get a very powerful heater...
