Poor air quality causes a range of very bad health outcomes, but we still know relatively little about the air we breathe. To address this problem, there are a growing range of commercially available air quality monitors including the very affordable PurpleAir and professional grade solutions from Quant AQ.
Gerrit Niezen adds an open-source monitor to the mix that has a low enough power consumption that it can run from a 5 Watt solar panel and connect to the internet via the Helium LoRaWAN network.
Details and files for the build are available on Hackaday and Github. Look for circuit boards on Tindie soon.
As more citizens and municipalities track air quality, we are more likely to take steps to reduce airborne pollutants and improve the air we breathe every day.
