A TEMPERATURE MEASURING SYSTEM
Abstract:Thermocouple is widely used in temperature measuring system. But when used in embeded system based on microprocessor, it has some drawbacks, such as nonlinea, cold-junction temperature compensation and so on.This paper simplify the design difficulty when applying thermocouple in the embeded system by using MAX6675.
Keywords: Thermocouple, temperature measuring, microprocessor, MAX6675
