I mean this is cool but the size claims are somewhat misleading. They only sell you a sensor element on flatflex PCB, then you need to add own metal cage for thermal dissipation and a lens, so the overall size is significantly larger.

This is great for flexibility but very impractical especially for DIY space. Hopefully small fully integrated modules on something like edgeconnector PCB come out soon enough.

Unless I misread, the lens is integrated, but Bosch recommends an optical window to protect the device. The integration guide is pretty comprehensive. Many fan-based air sensors require some specific enclosure considerations to separate the in/outflow.

Sparkfun sell a module with a ground plane + thermal pad as heat sink. This is suggested as OK by Bosch, though adding a small heatsink is probably a good idea, or just mount the enclosure on a metal surface.

		Ah I was looking at the integration guide but just skimmed it and I thought the window was a required lens. Thanks for the correction. (Can no longer storage edit my comment unfortunately)
