SCD-30 CO2 range

Post by trindt67 »

I see in the documentation that the SCD-30 has a maximum range of 10000ppm. In my application I am consistently getting readings much higher than that - up to 20000-25000. In my researching, I see that the sensor itself seems to have a range out to 40000ppm. So, a couple of questions:

1. Is the range of the SCD-30 actually 10000, or is that a typo?

2. If the range is indeed only up to 10000, what is the behavior beyond 10000? Is it simply that the accuracy is reduced, or are there other potential issues?

Good question.

The datasheet from Sensiron states accuracy is +/-30ppm in the 400 - 10,000ppm range.

https://sensirion.com/media/documents/4 ... asheet.pdf

Values outside that range will be less accurate. The full range is 0 - 40,000ppm.
