Fangming Ruan, Eugene You, Ruishan Zhou, Sheng Li · 2012
Sensor Network is the basis of Internet of Things. Self-powered wireless sensor network has distinct advantages used in building automation. Energy balance and power balance are considered in battery-free sensor module. Analysis is given on various application places of self-powered sensor. A simple formula was given to evaluate average current in self-powered sensor module. Energy balance of weekend was discussed for lighting system in office building based on energy store super-capacitor. Function of battery free wireless sensor module was described based on ambient energy harvesting principles. The new battery-free wireless sensor module was applied in lighting system of modern building automation for energy saving. The topology applying battery-free sensor module was given and briefly analyzed.
