Tracking Pollution and Social Movement

Although it’s not yet small enough to be suitable for widespread deployment, Shannon Spanhake’s pollution monitor is already generating a lot of interest. Calit2 engineer Don Kimball and his circuits lab colleagues constructed the prototype for sampling and transmitting the pollution data. As conceived by Spanhake, the device – dubbed “Squirrel” – is more than an exercise in shrinking a battery, sensor-on-a-chip and Bluetooth transmitter into something small enough to clasp to a belt or purse, and creating a software database and program to show current carbon-monoxide readings on the cell-phone display.
The wireless carbon-monoxide sensor sends data via Bluetooth to the cell phone, which displays current data on its screen and communicates the pollution levels to a master database.
