WHAT IS IT
The Air Quality Egg is a sensor system designed to allow anyone to collect very high resolution readings of NO2 and CO concentrations outside of their home. ¬†These two gases are the most indicative elements related to urban air pollution that are¬†sense-able¬†by inexpensive, DIY sensors.
The Air Quality Egg is developed by a community effort, born out of groups from the Internet of Things Meetups in¬†NYC¬†and¬†Amsterdam. ¬†We are designers, technologists, developers, architects, students, and artists. ¬†Read about the history of the development of this project¬†here¬†and¬†here.
HOW IT WORKS
1)¬†Outdoor sensors:¬†¬†A small electronic sensing system plug into the wall and sits outside your home taking regular readings. ¬†It has an RF transmitter, which sends the data wirelessly to an Egg-shaped base station inside.
2)¬†Egg base station:¬†An Egg-shaped base station, which gives this project its name, receives the wirelessly transmitted data from the sensor box outside. ¬†It then relays that data to the Internet via a wired Ethernet connection. ¬†The Egg also acts as a User Interface, so it also has an LED light and a button. ¬†These are configurable by applications which will be developed in the future by the community.
3)¬†Data sent to Internet:¬†The air quality data will be sent in real-time toPachube, an open data service, which both stores and provides free access to the data. ¬†The service includes embeddable graphs and the ability to generate triggers for tweets and SMS alerts (it looks something¬†like this), as well as a robust API which allows for developers in the community to unlock the potential of this new dataset by building mashups, maps, and applications.
