EQUATION 6-3:
The thermistor temperature sensor can measure the
temperature range from -100°C to 300°C. The
resistance of the thermistor sensor decreases as
temperature
coefficient). As shown in
forms a voltage divider with R
The thermistor sensor is simple to use and widely used
for the temperature measurement applications. It has
both linear and non-linear responses over temperature
range. R
