The use of electronic weighing equipment offers management with fast, accurate, and timely information that enables customers to get their products quickly. The fact that it's used across the board in the business speaks volumes about how well accepted it is. In reality, its use ranges from conventional retail to manufacturing and warehousing to postal, health, and transportation services. It's a really ubiquitous technology. Microprocessor-based single-point load cell weighing devices are difficult to develop and execute because they contain a large circuitry. They are also slow and have poor resolution. Microprocessor-based weighing scales that use faster microprocessors and higher resolution are also available. As a result, these gadgets are typically prohibitively expensive since they include a large number of external devices and processors. In another electronic weighing system, an 8-bit analogue to digital converter is used in conjunction with a microprocessor. To store programs, data, and variables, it is equipped with onboard memory modules. A compromise must be made between range and resolution in both circumstances. As part of this study, we discuss the design and execution of a digital electronic weighing system that may be used in the home, the laboratory, and commercially. A microcontroller chip is used to decrease the amount of wiring in the system. To store data from the ADC, an 8-bit 8051 microcontroller is used together with a local memory module. To obtain high resolution while yet maintaining a wide dynamic range, a serial 10-bit ADC must be connected to an 8-bit microcontroller through a software interface. This is because the microcontroller utilized has an inbuilt Serial Programming Interface (SPI) built-in. Displays the weight deposited on a single point load cell are shown on an LCD screen using an electronic weighing scale. 0-5 kilograms of weight may be measured using the system that was built.
