LPS25HB Pressure/Altitude Sensor Carrier

This carrier for ST?s LPS25HB digital barometer measures pressures from 260 mbar to 1260 mbar (26 kPa to 126 kPa) with absolute accuracy down to ±0.2 mbar (0.02 kPa) and typical RMS noise of 0.01 mbar (1 Pa) in high-resolution mode. These pressures can easily be converted to altitudes. The board has a 3.3 V linear regulator and integrated level shifters that allow it to work over an input voltage range of 2.5 V to 5.5 V, and the 0.1? pin spacing makes it easy to use with standard solderless breadboards and 0.1? perfboards. The sensor offers I²C and SPI interfaces.

Specifications:

• Interface: I²C, SPI
• Minimum operating voltage: 2.5 V
• Maximum operating voltage: 5.5 V
• Measurement range: 26 kPa to 126 kPa
