GL051 Air Quality Indicator

This document is a guide to making a portable device which can be used to monitor the air, in terms of PM2.5.

These tiny particles can come from a variety of sources and could be harmful. This device will indicate when the relative number of particulates in the air is high.  It could be used to monitor the air in a workshop.
