A high precision electronic scale based on Kalman filter was designed for the problems of traditional electronic scale with single function, slow data stability and low precision. The system takes STM32 as the main control unit, and introduces the implementation methods of each module in detail. Firstly, a high precision strain gauge weighing sensor is designed, and a more efficient data filtering algorithm is designed on the basis of this hardware. From the perspective of time complexity and space complexity of the algorithm, several common filtering methods of data in electronic scale are compared. Finally, some new functions such as networking and calibration are added on the basis of traditional electronic scale. The actual test results show that the performance of the electronic scale is stable, the speed of data stabilize is fast, and the weighing precision meets the national standard of three-level scale.
