This carrier for ST’s LPS25H 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 carrier for ST’s LPS331AP digital barometer measures pressures from 260 mbar to 1260 mbar (26 kPa to 126 kPa) with absolute pressure accuracy over temperature down to ±2 mbar (0.2 kPa) and typical RMS noise of 0.02 mbar (0.002 kPa) 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.

This sensor is a carrier/breakout board for ST’s VL6180X proximity and ambient light sensor, which measures the range to a target object up to 20 cm away (or 60 cm with reduced resolution). The VL6180X uses time-of-flight measurements of infrared pulses for ranging, allowing it to give accurate results independent of the target’s color and surface. Distance and ambient light level measurements can be read through a digital I²C interface. The board has a 2.8 V linear regulator and integrated level-shifters that allow it to work over an input voltage range of 2.7 V to 5.5 V, and the 0.1″ pin spacing makes it easy to use with standard solderless breadboards and 0.1″ perfboards.

Sparkfun’s carrier board for the HIH-4030 relative humidity (%RH) sensor from Honeywell outputs an analog voltage that varies nearly linearly with humidity. It operates at 5 V while drawing only 200 μA and has a 0.1" pin spacing that makes it compatible with standard breadboards and perfboards.
