Particle Squared, 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 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.
