摘 要
秤作为人们进行物品交换的中间工具,当前主要使用的就是电子秤,采用这种电子秤没有显示具体的数量,需要人们对其进行计算,同时,通过人们肉眼进行查看,人为主观因素较大。因此此次设计一款基于单片机的称重系统,该系统通过HX711对物品进行称重,该称重系统的精度可以达到0.1KG,除此之外此次设计还可以进行定量称重,用户可以根据自己的需求通过按键设置物品的最大值,当检测到当前的物品的重量大于设置的最大值时进行声光报警提醒,并将检测和设置的重量显示在LCD1602液晶显示屏上。
关键词:称重系统;HX711;声光报警;LCD1602
Abstract
As an intermediate tool for people to exchange goods, the current main use is the electronic scale, the use of this electronic scale does not show the specific amount, people need to calculate it, at the same time, through the naked eye to view, human subjective factors are larger. Therefore, this paper designs a weighing system based on single chip microcomputer, which weighs items through HX711, and the precision of the weighing system can reach 0.1kg. In addition, this design can also carry out quantitative weighing, and users can set the maximum value of items by pressing buttons according to their own needs. When the weight of the current item is detected to be greater than the maximum value set, sound and light alarm will be given to remind, and the detected and set weight will be displayed on the LCD1602 LCD screen.
Key words:weighing system; HX711; Sound and light alarm; LCD1602
