Electronic Thermometers
It is now common to measure temperature with electronics. The most common sensor is a thermoresistor (or thermistor).
This device changes its resistance with changes in temperature. A computer or other circuit measures the resistance and converts it to a temperature, either to display it or to make decisions about turning something on or off.
