Squirrel and Acorn
Cell phone Air Pollution Monitor
" ... Squirrel and the companion software, Acorn, also represent a bold exercise in social responsibility and cross-border engagement. "We want to make air quality data visible, accessible and legible to raise consciousness of environmental monitoring," says Spanhake. For this, she has collaborated with Calit2 researcher Kael Greco, author of a mobile webcam application that uploads images taken by the mobile phone automatically and continuously. These images are tagged and manipulated with the sampled pollution data -- the grittier the image, the more polluted the air is -- then displayed in real time on a web page. "This, along with other visual and audible ways, will help to demystify what 20ppm is in a meaningful way," says Spanhake, adding: "Low-cost technology will also make it available and scalable to the technological, environmental and cultural needs of individuals, communities and cities."
The device is low-cost, mobile, and scalable. It is also intended to be a building block for the creation of a mobile wireless sensor network dependent upon those who breathe the air -- people. "Squirrel is meant to monitor an individual's personal exposure to the air, thus providing a means for agency in the production of air pollution data," says Spanhake. "It will enable supplemental data to the environmental protection agencies that cannot afford to scale their technology to population growth and urban sprawl." ..."
