ECG sensor circuit without microcontroller...

[Kick]

Hiiii,
I have a doubt regarding my project.I want to design a Bluetooth based ECG sensor circuit but without uC, :drevil: is it possible to send data without uC? I have seen some topic like that.(I am not brilliant in circuit designing). :-(

Obvious question, why?

Sounds like a bad idea. You need a Bluetooth module that is able to talk to an AD converter, are you aware of a particular type that can do it? Eliminating data processing in the frontend involves more processing at the peer (e.g. PC application). If possible at all, it's just shifting programming effort, not saving it.

If you are good in programmable logic design, you can probably make a CPLD interface that translated ADC data to UART for the Bluetooth module. But I guess, you have no clue how...
