1  Using Arduino / Project Guidance / Re: Wireless transmission with piezoelectric sensor on: December 06, 2012, 10:49:41 am

maybe my initial message was not clear, what I need to do is to collect data from a PZT sensor with frequencies in the range up to 2-4 kHz. 10 kHz is just the sampling frequency used to avoid aliasing (in this case Nyquist frequency is 5 kHz). The number of samples used is around 8000. Then the signal acquired should be sent using wireless transmission, so I guess the piezoelectric sensor should be attached to the wireless board.

Most of application I have found for wireless systems use thermal data, which are of the order of hundred Hz of sampling frequency (much lower compared with vibrations).

Do you think that Alduino can be used for my purpose?

Hi All,

I need to measure vibration data from a piezoelectric sensor and send the signals via wireless transmission. Then, the time histories should be read the from my PC  (possibly) using a software application. The sampling time I set is around 10 kHz with approximately 8000 samples recorded.

Anyone knows if Arduino deals with such a problem or has anyone done something similar? If yes, any suggestion would be really helpful!!!

Naturally, if you need more information, just let me know.
