8 “Let's use the temperature sensor.”
Most of the microcomputer application systems contain various sensors to detect the external
information. There are various sensors for different purposes and requirements, and one of those
various sensors is the temperature sensor. The temperature sensor is, as its name suggests, a
sensor to detect changes in temperature. Examples of what the temperature sensor is used for
include the temperature control features of air conditioners and refrigerators. In this way, various
sensor s are used for household appliances.
This Starter Kit contains the temperature sensor.
temperature by using this temperature sensor.
8.1
The temperature sensor is a sensor to detect temperature changes. Simply stated it is a
thermometer to measure temperature. There are various methods to measure temperature. One
of those methods uses a mercurial thermometer, and another one uses a radiation thermometer
that enables contactless measurement. Table 8.1 Temperature measuring method shows
the general methods for measuring temperature. Of course it depends on the purposes or
requirements, however, most of the systems containing microcomputers use the thermocouple
thermometer or thermistor. This Starter Kit also uses the thermistor as its temperature sensor .

What is a temperature sensor?
Table 8.1 Temperature measuring method
Method and its feature
This method uses thermal expansion of mercury or alcohol to detect
temperature. This method is used for many thermometers and
clinical thermometers.
This sensor uses the Seebek effect. It contains the two-contact
circuit using two different metals, and when there is a difference in
temperature between two contact points, it generates thermal
electromotive force. It can measure the wide-range temperature.
This sensor uses the resistance thermometer bulb that uses the
temperature characteristic of semiconductor. It is in heavy usage.
The infrared energy emitted by an object varies with temperature.
The radiation thermometer uses this principle for measuring
temperature. It enables contactless measurement.
