基于单片机控制的电子秤设计

Electronic design based on single chip microcomputer controlAbstract As the primary component of this design,the microcontroller uses theprogramming language to design the software.After the measurement of the sensorsignal and signal amplification,the A/D conversion system will provide a signal to theCPU of the system,display the data through the LCD screen,and the keyboard inputsystem will be used to execute the operation command.When the overrange thresholdis used,the electronic alarm system Control may prevent damage to the electronicscale,achieve the basic utility of the electronic scale,easy to use,intuitive,accuratemeasurement,and meet the needs of modern social development at a low cost.The system uses the single chip AT89S52 as the main control chip,and the coreincludes the weighing circuit,the display circuit,the alarm circuit,the keyboardcircuit and the like to become the system circuit board,so that there is automaticcontrol of various control effects.Keywords:electronic scale,AT89S52,load sensor,A/D converter,
