   Thanks tomhow! The idea for building the Air Lab simulator was very much inspired by the feedback I got from you. Here is a bit of background for the other readers: I reached out to HN by mail (as suggested on their tips page) to gauge whet

   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 product and raise aw

   We'll definitely look into supporting Matter in the future, as it would allow integration with the most common home automation platforms/apps out there.

   We love indoorco2map.com and would be happy to ensure that data from the Air Lab can be exported to it! We plan to expose simple BLE characteristics for all sensor values (similar to the Aranet). On top of that, we already have an API that

   You can easily hook a PM sensor like the SEN54 to the extension port at the back. We're also thinking about offering an "upgrade kit" to match the design.

   As the sibling commenter pointed out correctly, there is no PM sensor built-in at the moment. However, we added an extension port at the back that allows connecting PM sensors like the SEN54. We also plan to support this natively in the fir

   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 for a device like

   Uff, that's hard! I'm sorry to hear that. What projects is yours?

   We have not tested this properly (see my other comment on lab testing), but so far we have observed no effect during normal operation and only saw a slight increase when charging the device (~1°). We took great care to move the sensors far

    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 air flow and particle

    Thanks! AirGradient is great! They do a very good job and served as an inspiration to us! On CO2-Sensor Accuracy: Based on AirGradients own research[1], the SCD41 (which Air Lab uses) and SenseAir S8 (which AirGradient uses), compare well i

    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 Supply projec

    This has been very tricky to navigate for us. We almost launched the campaign right before the Tariffs got announced. Luckily, we had the opportunity to wait it out. While CrowdSupply is an awesome platform, and I would use it again, the r

    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.

    Thanks for the feedback that I can totally understand! We hoped to offer the product at a lower price, but as I mentioned in other replies, it's hard to be competitive when planning for small quantities. That said, I can totally see us

    OP is probably comparing the ESP32 to a NRF chip. These offer Bluetooth connectivity while running from a coin cell with <1mA power consumption, compared to the ESP32s ~50mA when not sleeping. Luckily, we can stay in deep sleep most of t

    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 w

    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 can leverage economy

    Thanks! As other commenters suggested, there is a screen saver (after 30s idle) that shows all values (horizontal and vertical) at a glance. The layout is not final yet and something I want to improve (make bigger). You can try it in the si

    Thank you! Yes, that's something we'd like to prototype soon for supporting multiple rooms/locations. Integrating with other dashboards including TRMNL would be awesome too.

    That's correct if you just look at the component costs. Unfortunately, to make these in a small series, a lot of other costs come together. If we could, we would offer it a better price. Maybe some time soon!

    Yes, that's something I want to improve. ATM, if you rotate the (real) device, it will show a vertical layout in stand-by mode that uses a large font to display the values. I still need to add this to the simulator. A horizontal layout

    I found myself in a similar situation sometime ago with MongoDB. In one project my unit tests started slowing me down too much to be productive. In another, I had so little data that running a server alongside it was a waste of resources. I

    The licensing of a dependency could be easily determined programmatically (GitHub already built a decent scanner). However, I think that the quality of a dependency is most important and that requires a manual vetting process. A trivial sol
