PurpleAir sensor readings are virtually indistinguishable from government monitors according to new peer reviewed study
In August of 2016, the Gabriola Island Clear Air Society brought online the first PurpleAir sensor network in Canada. Our sensor network has documented extensively the staggering amount of air pollution coming from wood stoves and fireplaces on our tiny island. As the number of PurpleAir sensors expanded across the province and elsewhere in Canada, many began to raise questions about the accuracy of these low-cost devices. There have been several studies to-date that all show the same thing: these devices work, are accurate, reliable, and fill in gaps in air quality monitoring. The newest study from Australia by Dr. Dorothy Robinson provides definitive evidence that should quash any concerns about using PurpleAir sensors. See the study here . Gabriola Island Clean Air Society director Dr. Michael Mehta has the following to say about this study. This paper provides empirical evidence to show that the use of low-cost PM2.5 monitors for measuring air quality on a distributed basis has me
The local effects are staggering and patently unfair
We have a very serious wood smoke problem here on Gabriola Island, and there is no doubt that almost 100% of the problem is due to individuals burning wood at home for residential heating. Here's a snapshot from 10:30AM on October 10, 2016, of a new sensor in the Pat Burns area. This level of particulate matter exposure is very hazardous. Note the other readings in the region, especially the sensor only 400m away (as the crow flies) with a reading of 7 at the same time.
