    BME280 stops working. Shows humidity always 100%

    We prepared a board with BM280. Use a stevenson screen and place it in outdoor. 
    Board works fine for months, but now stops working, it returns humidity always 100%. Temperature and pressure values looks fine. 

    FYR, We used Adafruit BM680 library.

    Please help us to get this device working. 

    Thank you!

    Best Regards,

    Velmurugan S

    Hi Velmurugan,

     

    At the top of my head, since you mentionned that the sensor was placed outdoors, I woudl say the most likely cause of failure is corrosion due to condensation inside of the package. BME280 is not a sealed device and the operating range is only for non-condensing environments.

    I have the same problem as well.  Are you able to solve the issue? If yes, can you share with me the solution. I have been searching around the internet and seem a lot of people are having this issue that the humidity stuck at 100%.
