The Temperature Sensor Is Self-heating
Since the thermistor is a resistor and a certain amount of heat is generated when current flows through it, circuit designers should ensure that the pull-up resistor is large enough to prevent thermistor from overheating, otherwise the system measures the heat emitted by the thermistor, not the temperature of the surrounding environment.
The effect of the energy consumed by the thermistor on the temperature is expressed in the dissipation constant, which refers to the milliwatt required to increase the thermistor temperature by 1 degree Celsius higher than the ambient temperature. Dissipation constants vary depending on the thermistor's package, pin specifications, encapsulation material, and other factors.
The size of the self-heat and current-limiting resistance allowed by the system is determined by the measurement accuracy, which is greater than the thermistor self-heating that the measurement system can withstand with a measurement accuracy of .5 degrees C.
It should be noted that the resistance of the pull-up resistor must be calculated to limit the self-thermal power consumption over the entire measuring temperature range. Given the resistance value, the dissipation power varies at different temperatures due to changes in thermistor resistance values.
Sometimes the thermistor inputs need to be scaled to obtain a suitable temperature resolution, and Figure 3 is a circuit that extends the temperature range from 10 to 40 degrees C to the entire 0 to 5V input interval of the ADC.
The op amp output formula is as follows:
Once the input calibration of the thermistor is complete, the actual resistance and temperature can be charted. Since the thermistors are nonlinear, it is necessary to use a chart to indicate that the system needs to know what the value of each temperature ADC is, and whether the accuracy of the table is in increments of 1 degree C or 5 degrees C is determined according to the specific application.
