Description: The electronic scale is mainly controlled by the single chip microcomputer STC90C52RC, and realizes the basic control function of the electronic scale. The system can be divided into three parts: minimum system, data acquisition and human-machine interaction interface. The minimum system part mainly includes STC90C52RC and classic reset circuit, and the data acquisition part is composed of weighing sensor, signal amplification and A/D conversion section. The signal amplification and A/D conversion are mainly implemented by special type high precision 24 bit AD conversion chip HX711; the human-computer interaction interface is the keyboard input and the dot matrix LCD display. Using 4*4 matrix keyboard and 1602 LCD, you can input data and display data conveniently. The whole system has simple structure, convenient operation, complete functions, high accuracy and certain development value.
