Due to the drawbacks of the single function for the existing pedometers, this paper proposes an intelligent fitness partner based on the acceleration and photoelectric sensors. Through low-cost and single-chip three axles acceleration sensors MMA7260, it extracts and analysis the human’s sports information. Furthermore, it detects and analyses the human’s heart rate signal, by using the photoelectric sensor. Microcontroller PIC18F4520 is used to realize the algorithm of adaptive step counting model, and the heart rate detection circuit is also set up. The experimental results show that the proposed fitness partner can accurately display the heart rate wave of the testee, and the accurate rate is above 90%.
