Air Quality Egg (Version 1)

General Description

The Air Quality Egg is a sensor platform available based on an Arduino shield. The standard AQ Egg has four built-in sensors - Temperature, Humidity, Carbon Monoxide, and Nitrogen Dioxide. Additional sensors can be added to the AQ Egg. These add-ons include an ozone sensor (MiCS 2610/2611 sensor), particulate matter sensor (Shinyei PPD42), and a VOC sensor (MiCS 5521 sensor). The Egg tested in AQ-SPEC is the standard Egg with the ozone and particulate matter add-ons. A base egg receives information from the sensors and uploads it to the Internet.
