I came up with the idea of a hardware startup called AirGradient [1] focusing on indoor air quality monitoring due to annual recurring wildfires in my region and the wish to help my local school here in managing this better. Very soon I realized, I lack the experience on the hardware side and a partner joined in (so strictly not solo anymore). Yes hardware is hard! AirGradient focuses on monitoring indoor air quality in schools and offices and operates with a hardware as a service model, i.e. you do not have upfront costs for buying expensive sensor but you get the sensors provided for the duration of the service. I am also running a blog on AirQuality. I created detailed build instructions to build your own powerful air quality monitor (PM, CO2, Temperature and Humidity) which is fully open source and open hardware and I am more than happy to send you PCBs if you want to build it [2].
