Motivation • Natural gas is the most widely consumed energy source in
American homes
• Most gas is used by automated systems like furnace and water heater
• Most consumers are unaware of their gas usage
• Providing energy usage feedback to consumers typically results in a 5-20% reduction in consumption
How It Works
Results • GasSense is a low-cost system to provide appliance-level,
single-point sensing of gas activity in the home
• Deployed in 9 homes, recording 496 gas events, 175 in isolation, and 321 compound events
• Accurately detects and identifies 95.1% of gas events
Gas Appliance in Home is Turned On
Microphone Senses Gas Hissing
Detects and Identifies Gas Events
Filters Background Noise Regulator Hisses When Gas Flows

Motivation • Natural gas is the most widely consumed energy source in
American homes
• Most gas is used by automated systems like furnace and water heater
• Most consumers are unaware of their gas usage
• Providing energy usage feedback to consumers typically results in a 5-20% reduction in consumption
How It Works
Results • GasSense is a low-cost system to provide appliance-level,
single-point sensing of gas activity in the home
• Deployed in 9 homes, recording 496 gas events, 175 in isolation, and 321 compound events
• Accurately detects and identifies 95.1% of gas events
Gas Appliance in Home is Turned On
Microphone Senses Gas Hissing
Detects and Identifies Gas Events
Filters Background Noise Regulator Hisses When Gas Flows
Prototype Sensor Infrastructure Mediated Gas Monitoring via Single Point Sensing
