Dear HN community, thank you for the great feedback on my project! All comments, from honest remarks on the price to personal anecdotes on handling air quality issues, will help me, and others in this space, improve the…
Thanks! The SCD30 is a great sensor and obviously better than the SCD41. But we did not look at it in more detail, as we chose the SCD41 primarily for its small size. We believe that an accuracy of +/-50ppm is enough…
Uff, that's hard! I'm sorry to hear that. What projects is yours?
I'm curious, what's the range/variability you're seeing?
Thanks and good question! We have planned to do a proper lab test soon. The Swiss Federal Office for the Environment is a project partner and has such equipment. During the design phase, we used a software to model the…
Not yet. Unfortunately, these are usually quite big, and we didn't want to sacrifice the portability. But you can add a PM sensor through the extension port. We'll document this in our upcoming manual. A fellow Crowd…
Good catch! Unfortunately, we realized a bit too late that we flipped the standard console layout (e.g. Game Boy). Luckily, most people that notice get used to it quickly.
I have written a bit about the process here: https://www.crowdsupply.com/networked-artifacts/air-lab/upda.... TLDR: It compiles the stock firmware to WASM using emscripten. Thus, I did not build all of it in one week…
We added many components that are not strictly needed to measure air quality but make the device an interesting platform for custom projects. Also, the enclosure is more premium, being made from aluminum. Finally, IKEA…
