Open Air
open-air

This is an open source community effort to develop a range of low-cost air quality monitoring and remediation tools. Welcome! **Join in by:** * Reading about goals and asking great questions * Trying (and critiquing) our community-made how-to guides * Posting your own how-to guides and mods * Building on others’ work; hack and remix the kits to refine and expand them * Submit your improvements for inclusion in an upcoming starter kit release or add-on * Serving on a Research Review Group for a 3 month period **** ##Resources [State-by-state](https://publiclab.org/wiki/state-by-state-info-sheets-on-indoor-air-quality) info sheets on indoor air quality assistance and governance (work in progress!) **** ##Activities [activities:open-air] **** ##Frequently Asked Questions about air quality [questions:air-quality] **** Also see http://publiclab.org/wiki/air-quality ##Additional media By @zengirl2: https://blog.adafruit.com/2016/08/09/how-to-purify-your-air-with-hacked-plants-publiclab-citizenscience/ ...
