Abstract

Google released the Android 4.3 operating system on July 25, 2013.It ends the situation of manufacturers’ alone definition to Bluetooth 4.0, and supports low-energy technology. With the help of integrated chip CC2540 and mobile application, a low-power and smart Bluetooth scale is realized. Using the compression effect of resistance, it produces variational voltage signal. After AD sampling, those signals are sent to cellphone application which owns Bluetooth 4.0 function. When cellphone receives those data, it inserts them into the database. Since it supports multiple users, and owns function of automatic identification for the users. Through successful user login, selecting the authentication, reading data from the database, the system has two display modes, which are tendency chart and list view. What’s more, it can point out user’ condition of Body Mass Index based on the recent data.
