Analysis and Application of Power Balance in Self-Powered Sensor

Abstract:

wireless sensor network (WSN) nodes based on self-powered function have distinct advantages of battery free and no needing line power, used successfully in lighting control system of modern building. Energy balance and power balance are considered in design of battery-free sensor module. Average current in self-powered wireless sensor module was evaluated based on viewpoint of power balance. Energy balance was discussed in building lighting control system based on special energy storage of super-capacitor. Self-powered wireless sensor module is based on energy harvesting from ambient circumstance. In lighting control system of modern building automation battery-free sensor module has been successfully applied for maintenance and energy saving. The application of battery-free sensor module was analyzed.
