Design of MCU-based Intelligent Electronic Scale

Electronic scales are an important measuring tool with great market demand. As technology progresses and living quality rises, the needs for measuring accuracy, functional diversity and intelligence are increasingly growing. This paper designed an intelligent electronic scale to meet the requirements of measuring accuracy, portability and low cost. The design is consisted of six modules: which are measurement module, main control module, display module, alarm module, key module and Bluetooth transmission. The modules are described in details respectively. Through coordination of modules, the functions of tare and reset, buzzer alarm, accurate weighing are effected, and the data is uploaded to the mobile phone.
