I would like to know how to use bluetooth technology to transmit a chain of sinewave pulses from a magnetic sensor. The amplitude of these pulses will be 100 to 500 milivolts This signal would then be received by a bluetooth receiver circuit.
Don't think you're going to have much luck with the original signal. You will probably find that changing from AM with a voltage to frequency converter will be necessary.
Bluetooth is digital. You'll need to convert your information to a digital format for transmission. That will require a chip of some sort to convert the analog signal to digital, probably a microcontroller to receive that and convert it to something that can be sent bluetooth.
http://www.arduino.cc is a microcontroller coupled with the needed peripheral parts that can do the ADC and handle other tasks. The 10bit ADC can do most things but the arduino can talk to many ADC chips if you need better.
This is better than Bluetooth or Zigbee when considering range
280m (250Kbps); 150m (1Mbps) and price though you will need two and one will need an interface (arduino again or some other circuit) to talk to a PC http://store.qkits.com/moreinfo.cfm/TXRX24G
