Hi I have a central heating stove with couple of thermistors provided. It displays the temps on LCD but I wanted to hookup Arduino to have some historical data.
After plugging sensors into analog input, I have those RAW readings: Temp 1 reading: 270 [26 C on LCD display] Temp2 reading: 454 [54 C on LCD display]
I've tried couple of formulas for converting those reading to C but I can't find the right one.
I would appreciate any help solving this ;)
