We have developed a system to monitor and control water usage in residential homes. Our focus was centered around encouraging water conservation by giving users the ability to view their regular water usage and restrict their water flow as desired. Our system works by installing a node, which includes a valve and sensor, to the user’s desired appliance(s) in the home. The node is then connected to an Android application where it displays the usage data and gives the user control of the water flow through each node. The usage information includes trends of usage over time and the individual usage of each appliance. The application is connected to the node through WiFi, which allows the user to adjust the valve restriction from anywhere.
