BMP180 3D Model

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.

The BMP180 is designed to be connected directly to a microcontroller of a mobile device via the I2C bus. The pressure and temperature data have to be compensated by the calibration data of the E 2PROM of the BMP180.

The BMP180 consists of a piezo-resistive sensor, an analogue to digital converter and a control unit with E2PROM and a serial I2C interface. The BMP180 delivers the uncompensated value of pressure and temperature. The E2PROM has stored 176 bits of individual calibration data. This is used to compensate offset, temperature dependence and other parameters of the sensor.

· UP = pressure data (16 to 19 bit)

· UT = temperature data (16 bit)
