An Outdoor PM DIY Monitor
Do you think the current PM (Particulate Matter) monitors are too expansive or too risky to leave them outside? Do you need proofs for convincing your local authorities to take actions against air pollution?
Then it’s time to build your own personal outdoor PM DIY Monitor. It won’t cost you more than €32 and it can feed your community with valuable data about the air quality. Use that data to prove how bad is the air quality in your neighborhood or community.
