> the components for this project cost between $60-80
Purple air sells a turn key indoor air quality device for $200, is very reliable, also comes in a (clear) 3d printed case, comes with power supply. Not as DIY as this guy's solution, but with limited time on my hands the $100 was worth the cost of admission. It also works with Purple Air's map which provides nationwide air quality, temp and humidity, etc which is really nice.
It's worked flawlessly for me now for about five months. The light turns from green to yellow when I open the window in my south facing condo, but turns green again when I close the window and turn on the air filter. I was surprised at how bad the air quality gets when cooking food on the stove.
