Figure 1 shows an eZ430-Chronos sport watch, a product of Texas Instrument which has been widely used in various wireless applications.Zhou Z. [6] has developed the watch to be used as an electronic door locking device [6]. The watch was programmed to communicate wirelessly with the device attached to the door for the door to be locked and unlocked. This is done by tapping on the watch s 3-axis-accelerometer which is located on the watch s liquid crystal display (LCD). Thisproves that the wireless communication of the watch can be developed as long as the RF transceiver used is suitable for low power wireless applications. 

LabVIEW (computer) The ECG signal is processed by a system developed in LabVIEW to calculate and display the value of heart rate and oxygen saturation. It is also programmed to send the packets of heart rate and oxygen saturation data from the LabVIEW transmitter station via RE module (USB access point), which is wirelessly paired with the existing transceiver in the eZ430-Chronos watch. 

The developed LabVIEW program is able to send the calculated heart rate and oxygen saturation data in real time continuously to the eZ430-Chronos watch via a serial port through the USB RE module. The LabVIEW program(in run mode) will simultaneously interpret the input data and transmit them wirelessly to the watch.
