 "How to measure very low frequency?"...

You can also do this in the frequency domain.  The only trick is to
sample sufficiently low enough.  The lower your sampling rate, the
more resolution you will have for the low frequencies.  Just make sure
that you include an analog Low Pass Filter (ideally set to half the
sampling rate) before the A/D.  Once your signal is captured you can
either take an FFT of the signal or use the "Auto Power Spectrum" .vi
