The age of cheap, plentiful sensors, tracking everything from heart rates to the noise pollution slowly driving everybody insane is here. Joe Saavedra's modular neuroid is a wearable, reconfigurable sensor system that monitors pollution we probably don't wanna know about.
The modular part of the system is that it works with different kinds of sensors. Currently there are working sensors for methane, liquid petroleum, light and sound pollution, and carbon monoxide. The flagship device, built with an Arduino + Adafruit GPS system and three connection points for sensors, is a little bulky - more of a bag-hanger than a pocketable unit, but it's easy to see how it'll be miniaturised over time. It pairs up pretty nicely with a Nokia N900, as you can see.
Right now he's working with the New York Hall of Science to put it in the hands of middle and high school students - a beginning to his overall vision of citizen empowerment, where anybody can collect, view and collaborate on data from the world around us. Though, given how polluted NY is - in every way imaginable - maybe I don't wanna know. [Modular Neuroid, Parsons]
