Abstract
The following paper presents a design and implementation of heart rate monitor system based on the Bluetooth Low Energy technology of Bluetooth 4.0. The whole system is consisting of a heart rate sensor, a Bluetooth module and an iOS platform device that is embedded with Bluetooth 4.0. The heart rate sensor is able to acquire the heart rate signal of human body, and the Bluetooth module get the data of sensor, transmit the data through Bluetooth wireless link, the iOS device receive and process the heart rate data modulated in Bluetooth module, display the heart rate of human body on the screen. The results show that the implementation of heart rate monitor system based on Bluetooth Low Energy is more accessible for ordinary people than the dedicated medical device for the popularity of iOS device, the convenience of wireless link and the low power consumption of the Bluetooth Low Energy Technology.
