BMP180 general description
The BMP180 is the function compatible successor of the BMP085, a new generation of high
precision digital pressure sensors for consumer applications.
The ultra-low power, low voltage electronics of the BMP180 is optimized for use in mobile phones,
PDAs, GPS navigation devices and outdoor equipment. With a low altitude noise of merely 0.25m at
fast conversion time, the BMP180 offers superior performance. The I
2
C interface allows for easy
system integration with a microcontroller.
The BMP180 is based on piezo-resistive technology for EMC robustness, high accuracy and linearity as
well as long term stability.
Robert Bosch is the world market leader for pressure sensors in automotive applications. Based on
the experience of over 400 million pressure sensors in the field, the BMP180 continues a new
generation of micro-machined pressure sensors.
