This may be difficult to understand since I am not a native English speaker.
BME280 outputs barometric pressure, temperature, humidity, and altitude. The altitude value is obviously different because it is calculated by assigning these values to a single formula. Since the location of the sensor is fixed, I would like to assign the value obtained from the map data in advance and reflect it in the calculation of the barometric pressure, but I need some good advice. Thank you in advance.
