This pressure sensor from Freescale is a great low-cost sensing solution for precision measurement of barometric pressure and altitude. The MPL3115A2 has a typical 1.5 Pascal resolution, which can resolve altitude at 0.3 meters. It has interrupt outputs for ultra-low power usage, and it's also easy to read altitude with a built in altimeter calculation. There's even a fairly good temperature sensor with ±1°C typical accuracy (±3°C max). Click the link labeled 'Project Website' to find out more.
