BME680 Min and Max values of CO2e and b-VOC

[Carlos_Rafael]

Hi,

I’m using the BME680 sensor with BSEC lib. For my project specification, I need the minimum and maximum values of bVOC and CO2e in ppm. I couldn't find this information on the BME680 datasheet neither on the BSEC integration guide.
Could someone please help me on this issue?

Thanks

Hi Sir:

   Please see my comments:

    1. IAQ 0 - 500 adaptive IAQ, esp. for mobile applications; scales sensitivity based on recent environment (+-15) + (+-15%)

    2. CO2 400 - ... ppm estimates CO2 concentration (derived from VOC measurement, uses average correlation in field studies) no accuracy specified

    More information you need contact bst local FAE to get under NDA.

Hi Jet, thanks for your answer.

My question is a little bit more specific. If in my application I want to monitor just the results of CO2e and b-VOC, what would be the range of this values?

e.g.
CO2e = 400 to ...?
b-VOC =  0 to ...?

Thanks

Please see my comments:

1. IAQ 0 - 500 adaptive IAQ, esp. for mobile applications; scales sensitivity based on recent environment (+-15) + (+-15%)

2. SIAQ 0 - 10171 unscaled IAQ, esp. for stationary / special applications; uses fixed sensitivity scaling. no accuracy specified

3. BVOC 0.5 - 1000ppm estimates breath-VOC concertration to indicate current VOC level (derived form bVOC lab test) no accuracy specified

4. CO2 400 - ... infinity or limitless ppm estimates CO2 concentration (derived from VOC measurement, uses average correlation in field studies) no accuracy specified
