You ever find yourself sneezing inside your home and wondering “What the heck?! What is making me sneeze?”
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 buy 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 an Air Quality Wing.
The Air Quality Wing (Previously Particle Squared) is an all-in-one air quality sensor for Particle and Feather based development boards (development board not included). It brings together a trio of sensors to give you as many data points as possible. That way, there won’t be anything missing when you go to measure the air inside your home or workplace.
Here’s what’s included:
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.
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!
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.
No outlet nearby where you want to measure? No problem!
You can easily plug in almost any lithium polymer battery to your Particle or Feather based board and use it immediately. The Air Quality Wing has extra circuitry that allow you to use either USB or battery power. How great is that?
I have a similar setup I build with sensors off Adafruit and have been thinking of designing my own PCBA to integrate all of them, this saves me the time! Thank you! - Nicholas J
Thank you for integrating them on a single Featherwing format! - D
I love what you did to measure the air quality. - C
Headers are included but not soldered.
Shipping is a flat 5 dollars anywhere in the USA. Shipping can be combined for multiple.
