I am trying to use the BMP280 sensor from Adafruit. I have found the BMP280 library, have wired in the sensor and am getting readings, however the pressure reading is wrong. I am getting 84.1kPa but should be getting 92.6kPa. I have read where the altitude reading changes as the weather changes and can change the input value to correct the altitude.
The datasheet and Adafruit make it seem like there is no calibration for the pressure? Is this true? Am I forgetting something?
Could the sensor be damaged?
