Product description: Pressure sensor - barometer - QMP6988 - Unit expansion module for M5Stack development modules
Atmospheric pressure sensor in the form of a Unit type extension from the M5Stack sandwich module company. The measuring range of the QMP6988 sensor is between 300 hPa and 1100 hPa , the measurement accuracy is ±3.9 Pa . The resolution of the result is 0.06 Pa . Based on the pressure measurement, the sensor also estimates the altitude with a relative accuracy of ±0.039 hPa (±0.12 hPa, which corresponds to a difference in height of ±1 m). The module also has an integrated temperature sensor that returns data with an accuracy of 0.0002°C. The QMP6988 system is characterized by extremely high measurement precision and low power consumption.
The manufacturer has also prepared a user's guide , in which you will find a diagram of the system and sample program codes - check it out!

Botland is an official distributor of the M5Stack module family in Poland. We have extended this system of stackable functional devices with accessories from our range and numerous blog guides. All M5Stack products presented here are original.
Pressure sensor - barometer.
What does a barometer measure? What is atmospheric pressure?
The barometer is used to measure the total atmospheric pressure. Atmospheric pressure is dependent on weather conditions and varies with height above sea level. Wondering what atmospheric pressure is good for humans? The value of such pressure normal pressure is 1013.25 hPa and decreases with increasing altitude. Pressure above this value is considered too high and dangerous for humans.
