BMP180 Barometric Pressure Sensor
This 3.3v I2C sensor is super useful for measuring the absolute pressure of the air from the weather and altitude. No need to add additional pull up resistors as the unit comes assembled with SMD resistors. Requires some soldering for the header pins to interface with your microcontroller. This little unit is the size of the circumference of a AA battery and its ultra-low power consumption is a must have for accurate location based projects.
