BMP280 giving wrong pressure reading

[Anitha]

Hi 

We are using BMP280 in our design board. Initially, it gave the correct readings of the range of 950 to 1050 Pa. After usage of 2 months it giving wrong values of range 40 to 90Pa. I'm not sure what is the issue. Could somebody help to find the issue?

Hi Sir:

     Do you mean 40 to 90pa or 40 to 90hpa?

     Could you tell us in what environment the senosr was used? include temperature and pressure and other conditions.

     Do you tell us what did you do in two months? Do you power off and power on BMP280 or alway keep BMP280 running?

     Please offer more information to us.

      It is better to offer the entire sensor data from two months ago to now.

      Looking forward to your further inforation.
