Weighing system design based on 51 single chip microcomputer
This system uses single-chip microcomputer AT89S52 as the control core to realize the basic control function of electronic scale. It is mainly divided into five modules: object weight acquisition module, AD conversion module, MCU processing module, data display module and power module. The parameters are collected by four pressure sensors, the signal is amplified by the amplifier circuit, and the digital signal is changed by the AD conversion chip, processed by the MCU, and displayed on the LCD screen.
