For accurate temperature measurement, you must account for the inaccuracies of the electronics and the inaccuracies of the sensors.
Typically, most of the inaccuracy occurs at the sensor level. Temperature accuracy in uncalibrated sensors can range from as much as 2 degrees Celsius (in diodes and transistors) to 0.1 degrees Celsius (in precision glass thermometers).
