PRODUCT DETAILS
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 temperature accuracy is very high, as small as 0.0002°C.
