Hello Everyone , I am conducting some tests on the BME680 sensors and their respose to the enviroment, So for the test purpose I have placed two of the sensor exactly on the same location , and others are placed at some distance from them, I have let the sensors to run for 3 days,after three days , I have burnt some plastic material, in order to create smoky enviroment, the enviromentwas quite smoky,
What I found some strange things , the two sensors placed next to each other performs differently , Which I will show you on the graph , The two sensors placed almostly on the same location , then it should responeded to the enviroment in exactly the same way, but from the graph it behaves differently I just want to know the reason why this different behaviour is shown by the sensor that are placed exactly on the same location.
Note: I am using BSEC Library , and the sensors are operating in LP Mode, IAQ Configuration is : generic_33v_300s_4d, but because I am using LP mode of the sensor , the interval between readings is : 3 Seconds.
As you can see the sensor marked with white colour , are placed next to each other , but the graph shows different behaviour, This should be of same shape.
NOTE: This is the Static IAQ values reporting by the sensors.
Any help in regarding this will much be appreciated Thanks.

Need you confirm are they the IAQ output curves of sensors 1 and 2 respectively in the picture?
What are the accuracy values of the two sensors?

Yes Static IAQ Curves of sensor 1 and sensor 2 in the respective images . They are started at the same time and placed next to each other as you can varify from the timing in the x-axis , Initially the IAQ Accuracy was 3 , and then changed to 2 and then goes back to 3 for both sensors during this "Time Slice".
