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.
This sensor is a carrier/breakout board for ST’s VL6180X proximity and ambient light sensor, which measures distance with 1 mm resolution over a detection range of 0 cm to 10 cm or greater. The VL6180X uses time-of-flight measurements of infrared pulses to determine the range to a target object, allowing it to give accurate results independent of the target’s color and surface.
The SparkFun BME280 Atmospheric Sensor Breakout is the easy way to measure barometric pressure, humidity, and temperature readings all without taking up too much space. Basically, anything you need to know about atmospheric conditions you can find out from this tiny breakout.
