This is a demo of a lighting control system controlled by a battery-less switch. The sensors in the switch are battery-less and activated by wireless energy transmitters.
In this demo, four wireless energy transmitters, which works at 920MHz and embedded in LED lights, are employed and create a full wireless-energy-coverage space. All the sensors in this demo are battery-less and can be activated anywhere in the office by the wireless energy transmitters. The sensors measure the acceleration and angles, and then send the sensing data wirelessly to the BEMS server which controls the LED lights.
