Abstract :
The design of digital temperature transmitter based on microcontroller ADuC824 is introduced. With the peripheral feature integrated in microcontroller ADuC824 the hardware is simplified and reliability is improved. The interface of thermocouple with A/D converter in ADuC824 and RS232 interface with master computer is presented. The non-linear compensation and cold-junction compensation of thermocouple is provided.
