Maker Profile: Hamilton Mestizo

Hamilton Mestizo is the designer and maker of the Pollution Traffic Light, it detects levels of carbon dioxide and other toxic gases using sensors and conveys this information through the universally understood traffic light system. RGB LEDs connected to an Arduino through a custom shield (designed using Fritzing) power the device.

The project can be replicated for about £50 in materials and acts as an a functional sculpture to promote awareness and thought around the subject.
