Infrastructure Mediated Sensing

Disaggregated sustainability sensing measures the amount of usage from each fixture or appliance in a space-for example, providing information on the amount of water, electricity, or gas use at each point in the home. "The kitchen faucet was used 33 times today, for a total of 10 gallons." This type of information enables a number of end-use studies on sustainable water, gas, and electricity use, as well as enabling real-time eco-feedback monitoring. In this talk I will explain how we sense disaggregated usage using Infrastructure Mediated Sensing (IMS). IMS infers activity in a space or residence by sensing at a single point along a home's infrastructure (i.e., a pressure sensor for sensing whole home water use, a single microphone for sensing gas use, a plug-in sensor for electricity). I will give an overview of each system and give an extended explanation of our work in water sensing.
