基于蓝牙4.0计步器的硬件设计

A Hardware Design On Pedometer Based On Bluetooth 4.0

本文设计了一种基于蓝牙4.0低功耗(BLE)CC2540和三轴加速传感器BMA250E的计步器,包括运动检测、数据传输等。CC2540作为核心处理器,对加速度信息进行处理,并实现和智能设备的数据传输。BMA250E作为运动检测模块,可检测人体运动时的加速度变化。实验结果表明,此设计产品具有功耗低、结构简单、性价比高的特点,可投入市场使用。

This paper designed a low power pedometer based on Bluetooth 4.0 （BLE） CC2540 and triaxial acceleration sensor BMA250E, including motion detection and data transmission. The CC2540 is the core processor. It processes the acceleration information and achieves data transmission with intelligent devices. BMA250E is motion detection module, It can detect changes in body movement during acceleration. The experiment results show that the design of products with low power consumption, simple structure, cost-effective, and can be put into the market to use.
