The Indoor Air Quality (UK) HACS Integration and Sensor

Now that I have a number of AirGradient sensors around my house, I have all sorts of data I can make use of about the air quality inside it. I now have to figure out how to make use of all that data.

Using IKEA pm2.5 Air Quality Sensors in Home Assistant

I’ve been doing research on making some custom air quality sensors for inside and outside my house. The laser cutter is a main focus point for these as it would be nice to know how it affects air quality (and in the future, maybe activate an air filter based off the sensors readings). When I found out IKEA makes some simple air quality sensors that can be easily hacked using an ESP device, I decided to try it out.
