基于单片机与蓝牙传输的电子秤设计

Design of Electronic Scale Based on Single-Chip Microcomputer and Bluetooth Transmission

为了满足日常物品称重的需要,对电子秤进行了研究。在对主流电子秤研究的基础上,通过使用电阻应变式力传感器对5 kg以内的物品进行称量,以单片机AT89C52芯片为核心实现了物品重量采集、总价计算、超重报警、微调等功能,并可通过蓝牙实时发送数据至手机APP。实现了在日常生活中称重5 kg以内物品,满足了小超市出入库数据保存与监管的要求。

In order to meet the needs of daily items weighing,the electronic scale is studied.Based on the research of the mainstream electronic scale,the paper weighs items within 5 kg by using the resistance strain force sensor,takes the Single-Chip Microcomputer AT89C52 chip as the core to realize the functions of items weight collection,total price calculation,overweight alarm and fine adjustment and so on,and the data can be sent to the mobile phone APP in real time through bluetooth.It realizes the weighing of items within 5 kg in daily life,and meets the requirements of storage and supervision of warehouse in and warehouse out data of small supermarkets.
