Documentation 'Engineering_Guidelines_SEN5x' conflicting with implementation about arduino-gas-index-algorithm HOT 3 CLOSED

Hello @nickion

Your question is interesting, and I personally do not know much about this algorithm.
I will try to find someone who worked on this algorithm and then come back to you

Hello @nickion

After looking internally, there is a confusion in the document you are referring to, but the code is correct.

The gating threshold is at VOC index = 340 and NOx index = 30.
230 is the default gain

Therefore,
Q1: code is correct
Q2: code is correct
Q3: yes
Q4: yes as GasIndexAlgorithm_GATING_THRESHOLD_VOC

I hope it clarifies things for you. I forwarded the issue in the documentation and it should be fixed soon.

Many thanks Quentin for looking into this promptly. I've been working with the sensor and algo for some time in order to characterise behaviour in different scenarios, and good to know that it's only a documentation issue.
