Knowledge is power when it comes to saving electricity. Wireless Sensing of Circuit-Breaker Currents is a simple way to keep tabs on consumption, and take advantage of lower electricity prices when demand-response incentives kick in.
Most consumers have no way of knowing how much electricity is consumed by the many electric circuits in their homes and businesses. A simple system of wireless sensors — easily attached to circuit breakers inside a breaker panel — provides that key information. The inexpensive stick-on sensors are easily installed, requiring no wiring and no electrician.
They then go to work, reporting on the flow of electric current at each site, sending data to a secure repository on the Internet. Consumers can access this fine-grained, real-time information to make better decisions about electricity use and the dollars they spend on energy.
As utilities adopt dynamic electricity pricing — charging more when demand is high and less during hours of non-peak usage — sensor data will help customers pinpoint their costly behaviors. Do you sleep with the TV on, leave lights blazing in empty rooms, routinely run appliances during peak hours? Circuit-breaker sensors can help you change your ways, curb wasted energy, and save money.
