Product description
LPS22 is a compact barometric pressure and temperature sensor breakout based on the LPS22HB sensor. It is used to measure air pressure with high resolution to estimate weather changes or altitude above sea level. The sensor can deliver 24-bit pressure data and update up to 75 times per second, providing fast and stable measurements in both portable and stationary systems.
The breakout board includes level shifting and a regulator so it can be used with both 3 V and 5 V systems. Equipped with Qwiic connectors for quick connection without soldering. Breadboard friendly via pin headers (included but not pre-soldered). The sensor features built-in temperature compensation and high overpressure tolerance, making it suitable for everything from weather stations to altitude measurement in portable projects.
