According to Gerd vom Bogel, a scientist at the Fraunhofer Institute for Microelectronic Circuits and Systems in Germany and lead researcher on the project, “Our wireless window contacts draw all their energy from ambient radio signals.” This new system’s sensors will obtain its “tasks” from wireless radio signals that are sent out by controllers in each room. These room controllers will not only deliver juice to the window contacts, it will also collect data from them while performing a transmission of all the status of each room’s windows to a central device.
This central device will then rely on a wireless Internet connection that transmits the information to a homeowner’s notebook or smartphone. This might just make future smart homes much more fun to live in, don’t you think so?
