Open Source Outdoor Air Quality Monitor
I'm the founder of AirGradient and last year we have decided to focus our company on open hardware air quality monitors that we produce professionally.Our outdoor monitor Open Air has been designed from the start as an open hardware project with a beautiful plastic injected enclosure to demonstrate that open source hardware can look and perform on the same level like traditional products.We do also work intensively with research institutions around the world to test the monitor and ensure that the monitors are as accurate as possible [1].Happy to answer any question that might come up.[1] https://www.airgradient.com/research/
