The Design of Network Pedometer Based on Bluetooth 4.0

The pedometer combined with Bluetooth 4.0 can effectively implement the communication with the laptops, PAD? and mobile phones. it can more accurately calculate the number of pace through the method of real-time digital filter smoothing data curve, the design not only can enhance people's enthusiasm of taking exercise but also can effectively save communication resource. Because of the Bluetooth technology is in the 2.4 GHz band which is free spectrum [1], Bluetooth technology is bound to get more widely applications and more recognition, it can effectively put the data recorded by pedometer sent to the mobile phone and other modern terminal devices through Bluetooth technology, and then the data is uploaded to the cloud server to be saved through the terminal. This can increase people's interest in the pedometer, because the relevant data can be visible saved for a long time, it tracks more convenient for people to exercise and reach the effect of physical fitness. So it is convenient for people to track and compare the physical activity to reach the effect of physical fitness.
