Temperature Sensing

Temperature sensors are broadly used in many household devices and industrial machinery. Their purpose is to measure the current temperature in their proximity. Often they are used for precautionary reasons—to keep sensitive components from overheating, for example—or just to monitor changes in temperature.

There are several very common kinds of low-cost components to measure ambient temperature. One such component is a called a thermistor. It is a variable temperature–dependent resistor that has to be set up with a voltage divider circuit (see Chapter 6) to measure the change in a circuit's voltage. Other kinds are small integrated circuits (ICs), such as the LM35 found on the Google ADK Demo Shield, or ...
