In order to address the issues with traditional weighing tools, this design incorporates intelligence, automation, and user-friendliness into the control system of an electronic scale. The system is mainly controlled by a single-chip microcomputer, with the weight measurement part consisting of a weighing sensor and A/D converter, along with a display unit. This electronic scale is compact, simple in structure, and equipped with functions such as tare weight adjustment, unit price setting, and accumulation. It boasts features including multifunctionality, high performance-to-price ratio, low power consumption, simple system design, user-friendly operation, fast speed, accurate measurement, and high degree of automation. The system uses the AT89S52 single-chip microcomputer as the main control chip, with peripheral circuits for weighing, display, alarm, and keyboard, to form an intelligent weighing system circuit board, enabling various control functions of an automatic weighing system. It can be said that the electronic scale designed in this project largely meets the application requirements. Keywords: single-chip microcomputer; weighing sensor; A/D converter; LCD display
