Design of Digital Electronic Scales Based on Single Chip Microcomputer
This paper designed a microcontroller based intelligent digital electronics scale. Using AT89C52 microprocessor core for system control,and through using the weight acquisition module,signal conversion module,data processing module and display module and a series of signal acquisition and processing circuit to present weight information to the user. It provides boot intelligent calibration,automatic overweight alerts,and also a complete user function,and the system performance is stable,reliable,low cost and has friendly man machine interface and low power consumption,and can be widely applied to modern business in the market.
