I have an pulse of 0 to 5 volts that I want to send to my computer. I have a USB interface for it, but I need it to be wireless. Size matters. I need the the transmitter part to be as small as possible. The receiver can be any size. Because of that, the interface I have is already a little bigger than I would like. It would be exceptable to have the pulse go to the USB interface and then to a transmitter, but I would really like to have the pulse go straight to a transmitter. Is there any way to do this?
