- wkat4242 1y agoIt probably doesn't even need a board, you can just wire all the sensors in a box and solder the cables. Each sensor only has 3 or 4 and so does the display. But a board is cleaner and they're super cheap to get made in China unless you're shipping to the US I guess lol. I've built sensor boards like these too. But more with Dallas one wire sensors to measure temperature in different locations of central heating systems.
- benbojangles 1y agoWires are chaotic and a point of failure
- wkat4242 1y agoTrue but they do facilitate more flexible placement. I use them a lot for one off projects.
- benbojangles 1y agoHave you tried kicad
- wkat4242 1y agoNo I usually use CircuitMaker. I like their big footprint database.
- ssuds 1y agoFor sure. Was just curious as they started out with a super basic DIY setup https://www.airgradient.com/documentation/diy/ https://www.airgradient.com/documentation/diy/ (which can be implemented without the PCB even, as another commenter in this thread suggested) so I was wondering if there was a functionality you found was missing that sparked you to create this project!
- benbojangles 1y agoFrom reading their specs, my pcb uses higher spec components (esp32, scd41, sgp41), newer technology, better accuracy, more sensing capability (VOC, & N0x)
