| Summary: | To have a successful wireless sensor networks (WSN), we should have an energy supply which provided by batteries. Batteries have small size and provide sufficient energy for the motes, but batteries cannot sustain the energy for the (WSN) to operate long time. The reason is that the batteries have limit storage capacity and it used up by time. So to save the sustainability of the system we harvest energy from surrounding environment such as light, thermal, or vibration. All these are renewable and green types of energy that does not cause pollution to the environment. In our project, a solar energy harvesting system have been introduced to provide energy requirement for the (WSN) to operate. A photovoltaic (PV) module, solar charge controller and energy storage are elements that used for the solar energy harvesting system. And according to calculations, a suitable PV module, batteries, and solar charging circuit are determined. On the other hand to get the highest and the maximum efficiency of the energy harvested, we use a maximum peak power tracking or maximum power point tracking technique (MPPT), to charge our rechargeable batteries which for our project is lithium-ion battery. |
