Design of Height and Weight Measuring Instrument Based on STM32

In order to realize the intelligent measurement of human height and weight, and ensure the accuracy and speed of measurement, a set of intelligent height and weight measuring instrument based on single chip microcomputer is designed. The instrument uses STM32F103 as the main control chip, optimizes the hardware design, and adds touch screen, voice and other functions. The common digital filtering methods are analyzed, and the limiting filtering method and the recursive average filtering method are combined to process the signals of the ultrasonic sensor and the pressure sensor. The measured results of the measuring instrument show that the system is accurate and stable.
