Design of temperature measure system for variable sensitive temperature range

Abstract

In many engineering applications, temperature measure is absolutely necessary. A method of temperature measure in variable sensitive range based on PIC MCU is introduced in this paper, and the principles of design and key technologies related are discussed. The PIC16F877A is used as the system core in this design, and the related hardware and software are realized. This design has the following characteristics: flexibility, energy efficiency and less electromagnetic pollution.
