You can get the same measurements and even more from AirGradient. Those are a bit cheaper and much more solid devices. Not so focused on design, but rather on accuracy:

I´m not affiliated with them in any way, but I´m using their indoor and outdoor sensors since a few years by now, and I am very satisifed. Btw. their HW is opensource and you can choose between their SW or can flash anything else.
The measurement data of my outdoor sensor is publicly available:
