BMP180 Barometric Pressure/Temperature/Altitude Sensor
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.
