OaSense development began in the spring of 2015 in an effort to help my family save water during the California drought. The idea came to me in the shower one day, when I realized that a large proportion of shower time is spent doing things that don't require running water, like shampooing and lathering soap. Leaving the water running at over two gallons per minute during those activities seemed akin to leaving the water on while brushing your teeth, a definite faux-pas here in today's California. Since then, I have designed, tested, and thoroughly refined this idea into a product that I am proud to share with the world.
