for up to 3 bar with very good accuracy use an automotive MAP sensor off a turbocharged vehicle, gives a 0-5V signal.
They make so many of them they are quite cheap.

standard 1 bar map sensor is sensitive enough to use as a barometer..... you just made me realise how I can build my own barograph, I've always wanted one.
