| Abstract: | Metal thermal resistance is a kind of widely used temperature sensor,and platinum resistor is usually set for the criterion in temperature measuring. Based on ATmegal6 single chip microcompater as the core processor and Pt100 thermal resistance as the temperature sensor, a portable digital thermometer is designed. In this paper, the thermometer structure and working principle are described in detail and the design of relevant hardware and software is given out. The thermometer runs well in the test, and it has high liability, high precision,low cost,high response speed, and convenience to carry, which has a bright prospect of appiication and popularization. |
