The Adafruit SPA06-003 is an affordable barometric pressure and temperature sensor from Goertek, ideal for basic environmental sensing and DIY quadcopter builds. It measures 300–1100 hPa (approximately −500 to +9000 m above sea level) with ±3 Pa relative accuracy (~±0.25 m) and ±30 Pa absolute accuracy (~±2.5 m). Temperature accuracy is ±1 °C.

The surface-mount sensor comes soldered onto a STEMMA QT breakout board with a 3.3V regulator and level shifting, so it works with both 3.3V and 5V logic microcontrollers. The STEMMA QT connectors on each side are compatible with SparkFun Qwiic, allowing solderless I2C daisy-chaining with other sensors and accessories.
