Lesson 23 Barometric Sensor - BMP180
Introduction
The BMP180 is the new digital barometric pressure sensor, 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 3uA 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.
