Sensor-enabled embedded systems are redefining how future communities sense, reason about and manage utilities (water, electric, gas, sewage), roads, traffic lights, bridges, parking complexes, agriculture, waterways and the broader environment. With advances in low-power wide area networks (LP-WANs), we are seeing radios able to transmit small payloads at low data rates (a few kilobits per second) over long distances (several kilometers) with minimal power consumption. As such, LP-WANs have become both a target of study as well as an enabler for a variety of research projects. In this talk, I will describe our experiences in developing and deploying wireless sensing systems for energy-efficient building and smart-grid applications. I will start-off by discussing a number of hardware platforms and sensing techniques developed to improve visibility into buildings and their occupants. This includes new devices for occupancy estimation, demand-side management using electric water heaters and an assortment of low-cost and easy-to-install sub-metering devices. I then show how these devices can be easily integrated using an open-source platform called OpenChirp that provides data context, storage and visualization for sensing systems. Finally, I will go over a case-study where we electrified over 500 homes in rural Haiti with wireless smart-meters that now no longer require expensive and toxic kerosene for lighting.
