Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious right or left wing sources will be removed at the mods discretion. Supporting links can be added in comments or posted seperately but not to the post body.

You can easily build your own air quality sensor. It's a cheap and awesome science project and you can contribute to a global grassroot sensor network:

I have one running, AMA if you want
I only have one question: How?
Take a look at the website:

It looks complicated, but basically you are ordering some thing from AliExpress, connect it via cables (no soldering required), flash a firmware via a software, register an account, put in WiFi data and put it in a box.
And that's where the tariffs getcha. Can't share other people's data 'cause of Louisiana's anti-free-speech law; can't get your own data 'cause of Trump tariffs. Oh yeah, it's all coming together (the noose, that is).
