M5Stack Barometric Pressure 2 Unit (QMP6988)
Barometric Pressure Unit is a specialized unit equipped with a QMP6988 barometric pressure sensor, designed to measure atmospheric pressure and estimate altitude. The unit offers accurate and reliable measurements, with a relative accuracy of ±0.039hPa (equivalent to ±1m height difference). It provides a wide measurement range, allowing for precise monitoring of changes in atmospheric pressure.
In addition to its barometric pressure capabilities, the unit also features an integrated temperature sensor within the chip. This enables it to measure ambient temperature with exceptional accuracy, as small as 0.0002°C. The high-temperature accuracy ensures reliable temperature readings and enhances the overall precision of the unit.
With its combined barometric pressure and temperature sensing capabilities, the Barometric Pressure Unit is suitable for various applications. It can be used for weather monitoring, altitude tracking, environmental sensing, and more. The unit's accurate measurements allow for precise calculations of altitude based on changes in barometric pressure, providing valuable information for outdoor enthusiasts, weather enthusiasts, and scientific measurements.
Overall, the Barometric Pressure Unit with the QMP6988 sensor offers reliable and accurate measurements of atmospheric pressure, altitude estimation, and ambient temperature. Its high precision and wide measurement range make it a valuable tool for various applications where precise environmental data is essential.
