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. This product is a drop-in replacement for the original LPS25H pressure sensor carrier.
