It delivers ±1 hPa absolute accuracy and up to ±0.002 hPa relative precision in high-precision mode — equivalent to detecting altitude changes as small as 2 cm.\n\nThe sensor includes a built-in temperature sensor (±0.5°C accuracy) and configurable oversampling with an internal low-pass filter for the lowest-noise readings. It operates over a wide range of 300–1200 hPa and -40°C to 85°C, and supports both I2C and SPI interfaces. The breakout includes level shifting for use with 3.3V or 5V logic.\n\nKey Features\n\n\n±0.002 hPa Precision – Detect altitude changes as small as 2 cm in high-precision mode\n\n±1 hPa Absolute Accuracy – Know your altitude to within ~1 metre\n\nBuilt-In Temperature Sensor – ±0.5°C accuracy\n\nConfigurable Oversampling – Internal low-pass filter for low-noise readings\n\nI2C and SPI – Dual interface support with STEMMA QT / Qwiic connectors\n\n3.3V and 5V Compatible – On-board level shifting for Arduino, Feather, or Raspberry Pi\n\nOperating Range – 300–1200 hPa, -40°C to 85°C\n\n\nIdeal For\n\nDrone and UAV altitude hold systems\nWeather stations and environmental monitoring\nIndoor navigation and floor detection\nAltitude-sensitive robotics projects\n\n\nPackage Contents\n\n1× DPS310 barometric pressure sensor breakout with STEMMA QT connectors\n\n\n\nNote: STEMMA QT cable not included.
