Description

Barometric Pressure Unit is a barometer unit that uses QMP6988 barometric pressure sensor to measure atmospheric pressure and altitude estimation, with a relative accuracy of ±0.039hPa (±0.12hPa, equivalent to ±1m height difference), a wide measurement range, and an integrated temperature sensor inside the chip, while the Absolute temperature accuracy is 2°C.

Features

  • Built-in temperature and pressure sensors
  • High precision (pressure accuracy: ±0.039hPa; Absolute Temperature accuracy: 2°C)
  • Low current consumption: 21.4uA
  • Development platform: Arduino, UIFlow (Blockly, Python)
  • 2x LEGO™ compatible holes

Includes

  • 1x BPS Unit v1.1 (QMP6988)
  • 1x Grove Cable (5cm)

Applications

  • Indoor navigation (floor detection)
  • Altimeter
  • Weather forecast
