BME688: Altitude effect

[SensorManiac]

Hi all,

Do you expect to have a change in behaviour of gas resistance when you take the sensor to a higher altitude? i.e. at a pressure of 80kPa

I expect that the baseline should change due to the fact that you have less O2 content, not sure about the signal though.

Thanks in advance!

Hi SensorManiac,

Yes, there may be differences in gas resistance due to differences in O2 content at different altitudes. If working at high or low altitudes for a long time, the baseline is also different.

Hi Robin,

Thanks for your response. I guess Bosch didn't do such an experiment with the BME688 sensors right? 

Kind regards!
