I’ve looked at building one of these, but what new actionable information do you get? I’ve been wondering if it might say the room is dusty and then I could run the HEPA vacuum cleaner to bring it down. Or is this just for measurement geeks?

You can use the PM measurement that the sensor outputs to calculate the Air Quality Index (for Europe: http://airindex.eea.europa.eu/) and for example, make it send you a notification when the pollution level goes up, so you can turn on the air purifier or vacuum or open the windows.
