got to be a cheaper way than buying a $100 pressure sensor.
want to connect to a PIC to measure air pressure in a air cannon.
this is for an accuracy competition so the air pressure must be some what accurate.
thought about a digital tire gague but connecting and sealing air tight? then connecting to a PIC.
This air cannon, still in design stages will incorporate a muzzle velocity sensor (two photo transistors) with an LCD readout.
a wind speed measurement, would like a digital compass but them sensors are way out there in price.
thinking about a DIY digital compass? to determine adjustment for wind.
by knowing the projectile weight, air pressure and muzzle velocity, one can be pretty accurate in hitting a target consistently.
or at least give it a try..
any ideas??
