Digital, barometric pressure sensor
Bosch Sensortec
General description
The BMP085 is a high-precision, ultra-low power
barometric pressure sensor for use in advanced
mobile applications.
With an absolute accuracy of 2.5hPa and a noise
level of down to 0.03hPa (which is equivalent to an
altitude change of merely 0.25m) the BMP085 offers
superior performance. At the same time the BMP085
features ultra low power consumption of down to
3µA. This and the very small, ultra-thin package make
the BMP085 the sensor of choice for any mobile
application requiring precise barometric pressure
measurement, like for example mobile phones, PDAs,
personal GPS-based navigation devices and advan-
ced outdoor equipment.
The BMP085 sensor is based on piezo-resistive
MEMS technology for EMC robustness, high accu racy
and linearity as well as long term stability.
It comes in an ultra-thin, but robust 8-pin ceramic
lead-less chip carrier (LCC) package. The BMP085 is
designed to be connected directly to a micro-con-
troller of a mobile device via the I
The BMP085 is the direct successor of the success ful
SMD500 pressure sensor, that marked a new gene-
ration of high-precision digital pressure sensors for
consumer applications.
