BMP180

The BMP180 is the new digital barometric pressure sensor of Bosch Sensortec, with a very high performance, which enables applications in advanced mobile devices, such as smart phones, tablet PCs and sports devices. It follows the BMP085 and brings many improvements, like the smaller size and the expansion of digital interfaces.

The ultra-low power consumption down to 3 μA makes the BMP180 the leader in power saving for your mobile devices. BMP180 is also distinguished by its very stable behavior (performance) with regard to the independency of the supply voltage.

Applications

  • Indoor navigation
  • GPS-enhancement for dead-reckoning, slope detection, etc.
  • Sport devices, e.g. altitude profile
  • Weather forecast
  • Vertical velocity indication (rise/sink speed)
