The Shower Cow Traffic Light Timer is a playful water conservation tool that helps households reduce shower times through simple visual feedback. As the timer changes color from green to yellow to red, participants receive immediate cues about their water use, turning an invisible resource into a visible behavioral challenge.

The project draws on behavioral science principles including feedback loops, goal-setting theory, and habit formation. By providing real-time information at the moment of action, the timer helps bridge the gap between environmental intentions and daily behavior. The friendly Shower Cow character adds an element of fun and emotional engagement, making the experience especially effective for families and children. When implemented across schools, neighborhoods, or community campaigns, the system can create shared participation and measurable reductions in residential water use.
