What if every mobile device had an air quality sensor?
We are developing mobile sensing technologies that help communities gather and analyze environmental data. We hope that this hardware and software will empower everyday citizens to learn more about their environment and influence environmental regulations and policy.
We have developed various research prototypes, which are being used in studies such as a deployment on street sweepers in San Francisco and a deployment of a handheld device in West Oakland. Right now we are focusing our efforts on air quality sensing. Our hope is that our research prototypes will demonstrate the utility of embedding environmental sensors in commercial commodity devices such as mobile phones.
Technology
An increasing number of mobile devices have the potential to become personal environmental sensors. To explore this potential, we are developing research prototypes that can collect environmental data. Currently, we are focusing our efforts on air quality measurements. Our prototypes can be carried by individuals or placed on community vehicles such as street sweepers. We are also developing research software to allow people to share and analyze the data that has been collected.
