IKEA Vindriktning IAQ

IKEA Vindriktning + BME688 + SGP30 + WS2812 connected to an ESP8266 running Tasmota

I had the feeling that the air in my living room wasn't very good but had no way to actually measure it. So I bought an IKEA Vindriktning since I didn't really know where to start and it is a quite cheap device.
Since IKEA devices are known to be quite hackable I did a bit of searching and sure enough there were quite a few mods already. So I decided to put together my own version with a few more sensors and some lights and share my experience of the process.

Obviously this is not the first modification of a Vindrktning (see #IKEA Vindriktning PCB and #IKEA Vindriktning Daughterboard) but I think I did some unique things that are worth sharing.

See the project log Inspirations/references for more resources and the files section for my Eagle PCB design.

When starting the project I contemplated whether to just go quick and dirty and point-to-point wire everything and stuff it into the Vindriktning case or to go @lond's route and make it more polished. For just attaching the Vindriktnings PCB to an ESP8266 I would probably have point-to-point wired it but since I wanted to add sensors and LEDs the wiring would get too elaborate and a PCB would be the way to go, so might as well make everything a bit more polished. Meaning custom PCB, neat wiring, connectors, 3D printed LED mounts and LEDs for the additional sensors to mirror the Vindriktnings LEDs for displaying PM2.5 levels.

I started with a CCS811 and MCP9808 and then added a BME688 and SGP30 to be used in the final implementation.
