There have been just as comprehensive if not even more comprehensive sensor sets available for a really similar price. It's nothing unique. As building such boards is quite common, I too have assembled many similar boards for my own use, to monitor both indoors and outdoors air quality although I don't have any external stations to compare my values to but they're "calibrated" according to the same baseline across my setup and it allows me to keep an eye on different types of pollution - different gases, particulates, UV, noise and so on. Would be nice if all these platforms could be tied together.
