IKEA Vindriktning Smart Home Multisensor Mod

The IKEA Vindriktning is an excellent platform for smart home integrations. However, available mods are based on just adding a D1 Mini that "listens" to the PM1006 while the onboard PCB keeps control over both the sensor and the LEDs. As a result, much of the potential of this platform remains unused (such as controlling LEDs, turning the fan on/off at specified intervals, changing PM2.5 limits and color schemes, etc.). A lot more flexibility is possible by adding just a few more parts (and spending more time). This is why I designed this thing.

This thing is designed to make the Vindriktning a fully controllable multisensor for smart home applications with almost zero modifications to the original enclosure. You will just need to expand the cable guiding hole to ~4-5mm diameter so that it fits more cables.

In this design, the original Ikea PCB is removed, the LEDs are replaced by a 8x WS2812b board, and the everything is controlled by a D1 Mini. The current version also includes
