The thermistor is the resistor using the temperature characteristic of semiconductor. The
resistance value of the temperature sensor varies with temperature. This Starter Kit contains
the TDK's NTC thermistor (NTCG164BH103 ） for its temperature sensor. NTC stands for
Negative Temperature Coefficient, and this thermistor has negative characteristic of the
resistance value, which is reduced as the temperature rises. This section describes the
concrete method of detecting temperature by using this temperature sensor.
To use the temperature sensor and detect temperature, it is necessary to understand the
specifications of the sensor. The specifications of the sensor to be used (NTCG164BH103 ）
can be confirmed on the sensor data sheet, which is issued from the manufacturer. The data
sheet of the temperature sensor contains the information required for measurement. For this
time, the relationship between the measured temperature and the state of the sensor (resistance
value) is especially important. According to the data sheet, the relationship between the
temperature from 5 to 50
between measured temperature and resistance of NTCG164BH103 .
