摘　　要：电子秤技术的发展给人们的生活带来了极大的便利,尤其是基于单片机的电子秤的出现,更是有效提高了此类商品的精度。本文所设计的电子秤系统主要是以C8051F020DK单片机为控制核心并由电阻应变式传感器、A/D转换芯片HX711、矩阵键盘和液晶显示器共同组成。该电子秤可以方便的输入数据、直观的显示数据并实现累加、去皮、清零等功能,同时把重量、金额显示到液晶显示屏上,具有操作简便、成本低、稳定可靠等优点。The development of MCU （Micro Controller Unit） technology has brought great convenience to human beings in daily life especially the electronic scale-one application of MCU, which is a remarkable improvement in accuracy of relevant products. In this paper, CS051F02ODK MCU is the control center of the electronic scale. Other functional parts include the resistance stain type sensor, A/D conversion chip HXT11, matrix keyboard and LCD （Liquid Crystal Display）. Conductors can easily input data, and the electronic scale will explicitly display the output data. The system can count out the total price and do add, peeled, clear function and simultaneously show the weight and the total price on LCD. The electronic scale is easily conducted, economically manufactured, and steadily functioning.
