BME680 Q

[mgchoi]

Hello, Bosch

I have a few questions about BME680.

I'm working on a project with BME680
Roughly speaking, we're going to take in air, detect toluene with VOC, and calculate the pressure difference.

The first thing I'm curious about is
Since the air is sucked in, the pressure is negative, but the BME680 says it can only detect 300 to 1100 hpa, so is it not possible to detect the negative?

Second,
I want to check toluene with VOC, but is toluene registered in BSEC and can it be detected?

And thirdly,
May I know the name of the measuring equipment that is referenced for BME680 accuracy and measurement?

Thanks

Hi mgchoi,

The BME688 can detect more gas types than the BME680.
Please refer to our official information. We have no such opinion.
