Interesting points - I wasn't aware of the accuracy tradeoffs with smaller sensors, though as an engineer I should probably have anticipated it.

I've been messing around with air quality measurement for a while but haven't got anything for the day to day yet.

Been a long time admirer of the Airgradient project. What are your thoughts on the SEN5x Vs Plantower PM sensors?

We don’t have enough experience with the SEN5x yet to give an opinion but it’s definitely a good sensor.

It might be better than the Plantower but on the other hand we know the Plantower really well now after 10s of thousands of units going through our test chamber. This allows us to tweak the Plantower to really good performance.
