    when i made an Airspeed and altitude recorder for my RC planes, i used an opamp between the pic and pressure sensors.. it worked well, if i can find the documentation for it, i will post it...

    if you search for model rocket altimeter schematics, you will find lots of people that have used pressure sensors with PICs.
