BMP085 High-Precision Barometric Pressure Sensor from Bosch Sensortec GmbH

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 advanced outdoor equipment.

The BMP085 sensor is based on piezo-resistive MEMS technology for EMC robustness, high accuracy 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-controller of a mobile device via the I2C bus

The BMP085 is the direct successor of the successful SMD500 pressure sensor, that marked a new generation of high-precision digital pressure sensors for consumer applications.
