Altimetric pressure sensors
1. Descriptions of Altimetric Pressure Sensor Modules HP203B:
The HP203B 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 5.3 μA per measurement-second while the ADC output is filtered and decimated by 256. Pressure output can be resolved with output in fractions of a Pascal, and altitude can be resolved in 0.1meter. The HP203B is offered in a 3.6mm x3.8 mm x 1.2 mm package and specified for operation from -40°C to +85°C.
