Adafruit LPS22 Pressure Sensor - Qwiic

The LPS22 is the Worlds Smallest sensor (according to ST) and it is surprisingly tiny - only 2x2mm. It has a wide measurement range of 260 to 1260 hPa with 24-bit pressure data measurements that can be read up to 75 times a second (Hz), you can be confident that you always have an up to date and precise measurement. It's pretty dang accurate too, with the ability to measure absolute pressure within 0.1 hPa after one-point calibration (± 1 hPa before calibration).

The ST LPS22HB (LPS22) can quickly and easily measure this air pressure, useful when you want to know about the weather (are we in a low-pressure or high-pressure system?) or to determine altitude, as the air thins out the higher we get above sea level.
