PRECISION BAROMETER AND ALTIMETER SENSOR
Descriptions
The HP209 employs a MEMS pressure sensor with an I²C interface to provide accurate temperature, pressure or altitude data. The sensor pressure and temperature outputs are
digitized by a high resolution 24-bit ADC. The altitude value is calculated by a specific patented algorithm according to the pressure and temperature data. Data compensation
is integrated internally to save the effort of the external host MCU system. Easy command-based data acquisition interface and programmable interrupt control is
available. Typical active supply current is 5.3μA per measurement-second while the ADC output is filtered and decimated by 256. Pressure output can be resolved with
output in fractions of 0.1 Pascal.
