    BME280 incorrect readings

    Re: BME280 incorrect readings

    Hi,

    I have downloaded the spreadsheet, put the calibration values that I read from device into the spreadsheet, and I am getting the same biased results.

    Waiting some delay (about 500ms) helped a bit, as the first and second reading are now not as far as it was from the reading when device stable. But the values the sensor reports are wrong.

    What could cause me reading ~32 degrees C instead of room temperature ~25.0 C?

    The sensor is not placed close to any of the processors on board so no heat source near it. When I put my finger on the sensor I see the values rise quickly, so it looks like the sensor is working. But why is it giving such biased values?

    Hello BenShapiro, 

     

    Did you test with latest our github and example setting? 

    Could you test with my attached code? 

    I got stable data from start. 

    Thanks 🙂
