Air Quality Wing for Particle Mesh 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 on board:
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 Si7021temperature 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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
