EQUATION 6-3:
The thermistor temperature sensor can measure the
temperature range from -100°C to 300°C. The resis-
tance of the thermistor sensor decreases as tempera-
ture increases (negative temperature coefficient). As
shown in
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
for measurement.
