    BME680 long term measurement changes

    BME680 long term measurement changes

    We have a product using the BME680 and I was comparing the temperature and humidity reported from some recently built units (a couple of months old) vs. a group of units that are over two years old.  The new group all report temperature and humidty that roughly agree with each other.  The same for the old group.  But the values for new vs. old are quite different.  Based on what I'm seeing it appears that as the sensors have aged they report higher temperature and lower humdity.

    Is there a known expected change in the values reported as the BME680 sensor ages?  If so we can adjust the reported values accordingly.

    Hi mitchkapa,

    We don't have such data or guidelines. The sensor value of BME680 will be within the specification range. You can use the official hardware and software  board(application board 3.0 + BME688 shuttle board 3.0) for comparative testing.
