I am measuring air pressures inside of plastic tubing with a battery =
powered microcontroller. Since the air is moving, it builds a static =
charge on the plasic tubing. My plastic pressure sensors (Motorola MPX) =
are connected to the tubing with vinyl tubing. I am wondering if there =
is a need to supply a discharge path for static buildup. I was thinking =
of some metal couplers on the plastic tubing, grounded with a wire to =
some ground point, like a water pipe. But perhaps I could just ground to =
the negative battery terminal?

Thanks

John
