Abstract

In order to meet the needs of multi-point temperature auto measurement data storage for the industrial production

four-channel temperature measuring circuit is designed by using MSP430F449 as the main controller and Pt1000 as the temperature sensor.The temperature signal is sampled from the single bridge which is supplied by a constant voltage power.In the mean time

the hardware circuit based on SD card and the temperature data storage system based on FAT16 is designed.The hardware and software design method of the measure module

the storage module

the communication module and the auxiliary module is given in this paper Temperature measure experimentation result shows the system can reach 0.03℃ in the range-23～100℃.The result also shows that the system is reliable and portable

and can meet many needs of multi-point temperature measure.
