A new feather board is now available in the form of the Air Quality Wing for Particle Mesh which is available to purchase from the GroupGets website priced at $36.25. The new board offers an all-in-one air quality sensor for Particle and Feather based development boards which are available to purchase separately. The small add-on board brings together a trio of sensors to give you as many data points as possible.
Particulate Sensing – The most important sensor is the Honeywell HPMA115S0 dust sensor (available as a purchase option). This sensor counts the concentration of potentially harmful particulates in the air. It can detect both large particles 10µm in diameter and smaller ones less than 2.5µm in diameter. These readings are known as PM10 and PM2.5 respectively.
Sensing Volatile Compounds – Second to that, is the AMS CCS811. This senses volatile organic compounds and eC02. These types of readings are useful in places where there may be combustion. (Think stoves, furnaces, etc) It can act as an early warning mechanism. That way you stay safe, happy and healthy!
Temperature and Humidity – Finally, the Silicon Labs Si7021 temperature and humidity sensor. These readings can be used on their own. Additionally they’re used by the CCS811 to compute an accurate TVOC and C02.
Jared Wolff designer and creator of the Air Quality Wing for Particle Mesh board explained a little more about the inspiration behind it.
“You ever find yourself sneezing inside your home and wondering “What the heck?! What is making me sneeze?” I had that same question. After wildfires have ravaged parts of the USA and smog has loomed in our skies it’s become more important than ever to make sure you’re breathing clean air. Some folks may just go by an air purifier. But, how do you know it works? How do you know if it’s powerful enough to protect your whole space? Like a scientist, you can test it with the Air Quality Wing for Particle Mesh.”
