Abstract
Introduced a new system about temperature-collecting,as well as the concrete hardware circuit and software.Hardware includes DS18B20 temperature-measuring,MCU communication,communicating interface circuit of PC and used MCU.VB,MCU assembly language and PC serial communicating technique,a system is made out for software.The system is proved that the accuracy can get to ±0.01 ℃ and that it can communicate with MCU and PC steadily.
