After simply installation onto a distribution board, the Life Pattern Sensor (LPS) detects the total power consumption in a home, as well as the usage status of individual electrical appliances. The LPS records the signals of each appliance and detects the current waveform of appliances that are in use, making their power consumption visible. If all a home's appliances are operating at the same time, for example, the LPS can show how long each appliance has been running. The ability to see home power consumption at a glance allows a homeowner to detect waste, playing an ongoing role in energy conservation.
