Pulse Rate monitoring in PC (wireless)

This circuit is used to display the number of pulses occurred per minute on the PC desktop.we can use this to calculate frequency of the signal. 

Working: i will calculate the signal peaks every minute and i will send that information using wireless protocol(Gigbee/GSM). on the other end i will receive by the same wireless device and i will send the same data to RS232 port of a PC. You can monitor the data on Hyper-terminal.

     

                                                                                                             

You have to connect wireless device GSM/Gigbee on both sides. depending the device connected you have modify your code.                                                             

NOTE: i haven't indicated any wireless device. that will be connected to DB9 port.
