BME688 development kit data

[Grayson]

Hi,

three question about bem688 dev kit:

1. does this sensor has baseline drift? or it has been solved. after a long time of use, will this sensor has baseline drift because of the Mox react with other gas.

2.the 8 sensors on the dev kit is using the same  metal oxide or the different?

3. can I splite the data from which sensor of those 8 snesors?

Thank you,

Grayson

Hi Grayson,

1.Have you actually tested it? If you find any issues during the testing process, you can provide us with detailed information.
2.The 8 sensors on the BME688 dev kit are the same.
3.The demonstration code for the BME688 dev kit is publicly available, and the default is to collect data from 8 sensors. If you need to splite sensor data, you can modify the code yourself.

Hi,

I try to use the dev kit in the air for one day and read the resistance, it keeps around the 3e7 for 1000mins, the next 600mins it went up to 3.5e7.

2.one more question, can you provide me the detect range of BME688, I did't see it in the datasheet.

Thank you so much!

Hi Grayson,

Do you mean the gas resistance range? If yes, you can refer to the minimum and maximum values output by BSEC_OUTPUT_RAW_GAS.
