This pressure sensor from Freescale is a great low-cost sensing solution for measuring barometric pressure. The sensor is soldered onto a PCB with 10K pull-up resistors on the I2C pins.
This chip is good for use with power and logic voltages ranging from 2.4V to 5.5V so you can use it with your 3V or 5V microcontroller.

TECHNICAL DETAILS

PCB weight: 0.61g
Vin: 2.4 to 5.5 VDC
Logic: 3 to 5V compliant
Pressure sensing range: 500-1150 hPa (up to 10Km altitude)
1.5 hPa / 50 m altitude resolution
This board/chip uses I2C 7-bit address 0x60

When using with an Arduino, simply connect the VDD pin to the 5V voltage pin, GND to ground, SCL to I2C Clock (Analog 5 on an UNO) and SDA to I2C Data (Analog 4 on an UNO). Then download our MPL115A2 Arduino library and example code for temperature, pressure and basic altitude calculation. Install the library, and load the example sketch.
