Adafruit LPS28 (LPS28DFW) Pressure Sensor - STEMMA QT / QwiicThe Adafruit LPS28 (LPS28DFW) Pressure Sensor is designed for applications requiring measurement of a wide range of pressures, including deep water and high altitude. Unlike many pressure sensors that max out at about 1260 hPa, the LPS28DFW can measure pressures up to 4060 hPa, equivalent to depths of 40 meters underwater or altitudes down to 43,000 feet below sea level in air. This sensor provides high precision with absolute pressure accuracy of 0.
