' Measures voltage across the thermistor and uses a combination of table lookup ' and linear interpolation to calculate the temperature in degrees C. ' ' Sends temperature to PC (or similar). Thermistor is an electronic component used to calculate the temperature.This is a type of resistor whose resistance varies with change in temperature. I used a Vishay spreadsheet to calculate the min and max resistance value for each degree. Low temperature storage After placing a thermistor in -40â±3â for 1000 hours, keep it in normal temperature and humidity for one hour. The resistance in 25 °C is 10K (+- 1%).
