An increasing number of areas face a major water shortage — several cities in Brazil and the state of California for instance. The impact on domestic users and industry is rapidly becoming critical. Although the authorities there are working on physical strategies to solve this problem and educating users to save water, we still lack information on our water consumption in real time. What’s needed is data acquisition through a web interface.To address this situation we created the WaterDeck project, a solution for monitoring and analyzing water consumption in smart cities (and beyond!), using Freescale and ARM technologies.
