This thesis is to design and develop the energy harvesting wireless broadcasting system using indoor lighting as power source. The experimental wireless signal broadcaster is integrated by solar cell charging subsystem, electric power management module, MCU controller module and Wi-Fi module. We propose an indoor positioning system based on such broadcasting system. In order to manage the limited harvesting electric power, we implement a dual-capacitor electric power management module to achieve stable system operation. After the preliminary verification and system test, the concept and system design of the wireless broadcasting system are feasible and the system is very suitable for environmental surveillance applications.
