Measuring Temperature with the PIC16F84A Watchdog Timer Application Note

From Microchip Technology, Inc.
 

 
Almost all temperature sensor circuits use some form of discrete component (such as a thermistor or a solid-state sensor) to actually measure the environment?s temperature. It is left to the microcontroller to interpret the reading into a human-friendly form for the users benefit. It is possible, however, to design a digital thermometer without an external sensor, by using a temperature sensitive property of the microcontroller itself. This Application Note shows how to use the Watchdog Timer (WDT) of a PICmicro ® microcontroller for temperature measurement.
