It is possible to filter, but it is necessary to understand precisely that you want to throw out. records also experiment with filters. The most simple .. Type filters y [i+1] =q*y [i] + (1-q) *x [i] where q=exp (ln (th)/n), n-number of measurements on which on history will be an accuracy threshold for example %0.1 th=0.001 we take energy of a signal (a dispersion) (x [i+1]-x [i]) ^2 as is smoothed for example on 4 measurements and on a threshold is defined when rings....

"Server" on earlier thought to make, but it turns out more expensively than to buy all ready, and trouble only with a software in this case. There are arduin and sensors sensors +-0.5S or most on any msp430 to collect and in hermetic a box to thrust.
