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 I2C 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. 销售热线：0 1 0 - 5 9 4 5 7 5 6 9 1 8 0 0 1 2 9 9 5 3 8 陈先生Data sheet BMP180 Page 4 BST-BMP180-DS000-07 | Revision 2.3 | May 2011 Bosch Sensortec Bosch Sensortec GmbH reserves all rights even in the event of industrial property rights.
