Description
The Barometric Pressure Unit is a barometer unit that uses a 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.
Features
- Built-in temperature and pressure sensors
- High precision (pressure accuracy: ±0.039hPa; Temperature accuracy: 0.0002°C)
- Low current consumption: 21.4uA
- Development platform: Arduino, UIFlow (Blockly, Python)
