Smart electronic scale is a new type of weighing instrument that combines computer communication technology and digital conversion technology. Designed and implemented here. A smart electronic scale based on 51 microcontroller was developed. This smart electronic scale mainly contains 5 major modules, namely display module, Bluetooth module. 

  Main control module, power module and sensing module, and each module is explained in detail. Each module is linked to achieve taring, restoration, and accurate weighing, function and upload data to the mobile phone. Stable and reliable weighing application combined with host computer management software and ultra-small keystrokes. Sensitive and accurate, it can continuously meet various needs for weighing to a certain extent.

  Traditional electronic scales mainly measure the mass of objects, using the principle. It's Hooke's law or the principle of lever balance. But with modern. With the development of communication and IT technology, traditional electronic scales can no longer fully satisfy people's needs. Their needs for weighing. At present, some smart scales can automatically identify the products on the scale, and the recognition is fast.
Fast and accurate, adaptable to different lighting environments and various packaging methods; and another. Some smart scales support intelligent identification and product retrieval, lowering the operating threshold. Learning results can also be shared across stores, simplifying multi-store deployment and improving practice. Improve implementation efficiency, reduce maintenance costs, and implement remote deployment and over-the-air download technology (OTA) upgrade. Smart scales because of their excellent hardware quality and artificial intelligence. (AI) technology can ensure long-term stable operation of equipment. Some developers use. Using intelligent algorithms to combine weighing with visual recognition and picture shooting, you can Simplify handling and achieve error-free operation in pick and pack applications. Connect smart scales directly to production and enterprise resource planning (ERP) systems. system that ensures full data visibility and provides users with information about successful fulfillment. Intuitive proof of order . In order to achieve accurate measurement, develop with advanced awareness. development and design, with the main goal of achieving the best quality, designing and implementing a. A smart electronic scale based on a single-chip microcomputer . 2 Problem raising and demand analysis.

The designed smart electronic scale enters the welcome interface after being powered on -"Welcome to this smart electronic scale design". When there is an object on the stage. When , the ADC0832 chip immediately sends the data conversion to the microcontroller for processing. And displayed by the liquid crystal display (LCD). The user inputs the corresponding product using buttons. After the code number, you can see the name and order of the corresponding product on the LCD.
Price, total weight, total price and other information. In this design, it is particularly important to point out. Yes, the weight of the object to be weighed may exceed the range of the electronic scale. In this case, you should Let the electronic scale issue a voice prompt to protect the electronic scale and extend its service life Life. Its measuring range is designed to be 0~9.99kg.
