Particle^2 (pronounced Particle Squared) is a circuit board that helps you monitor the air quality around you. (Originally posted about it here.)

This sensor board allows you to monitor humidity, temperature, air particulates, eC02 and TVOCs in one small package. You can use it with an Adafruit Feather compatible board or the newest mesh enabled boards from Particle.

Plug it into a battery pack and put it almost anywhere. Outdoor applications may require a separate enclosure to protect the electronics.
