The BMP180 is a sensor that measures temperature to 0.1 °C precision and barometric (atmospheric air) pressure to 1 Pa precision. The device has been designed by Bosch Sensortec and comes with an I2C interface. The data sheet with a complete description of the chip and how it can be programmed can be found here. In addition to the sensors themselves the device features a 176 bit EEPROM containing individual calibration parameters for each device.
