Electrical Device Energy Usage with a Single Sensor

.

Overview

ElectriSense is a single plug-in sensor that provides whole home device level usage data. That is, using a single sensor plugged in anywhere in the home, ElectriSense can infer which electrical appliances are on and which off. This data could be used for numerous applications, for example, for providing home owners with itemized electrical bill that not only shows the total energy consumption but breaks the total on a per appliance basis (TV consumed 20 KWh, Lighting consumes 18 KWh and so on).
