Adafruit DPS310 Precision Barometric Pressure / Altitude Sensor - STEMMA QT / Qwiic Coral USB Edge The MPR121 operates via I2CHow high are you right now? If you had a precision altitude sensor, you would know for sure! The DPS310 sensor from Infineon a high precision barometric sensor, perfect for measuring altitude changes with a up to 0. 002 hPa (or 0. 02 m) precision high precision mode and 1 hPa absolute accuracy. That means you can know your absolute altitude with 1=meter accuracy when you set the sea level pressure, and measure changes in altitude with up to 2 cm
