摘要：The designing scheme for PIC24F-based miniature temperature recorder was summarized and MCU was introduced. The scheme included sensitive compo-nents, MCU （PIC24FJ128GA106）, as wel as the PC terminal for settings, col ec-tions and temperature read as wel as data processing. And the principle of design was introduced, including measurement module introduction, real-time clock and de-vice calibration section. This paper provided a theoretical basis for the application of PIC24F-based miniature temperature recorder.
