Hello, I'm trying to use heated bed 120x120 mm^2 demension in the picture. The provider said it has a thermistor but they don't know the specific name of it. I searched on internet but also I could not find the datasheet of it. Therefore, I planned to measurement and fitting the sig voltage-temperature and designed experiment. I used multimeter and found the ciruit schematic of thermistor. Iby Raspbie - General
