PIC-Based Solar Energy Harvesting Module Design for Wireless Sensor Networks

Nowadays, the issue of power consumption is very important in wireless sensor networks (WSNs) and recent developments have allowed solar energy power to be used for WSNs. How to collect and store energy effectively from the environment has been investigated for the WSNs in this paper. Energy consumption issues in the WSNs is the most significant constraints of the wireless sensor node systems. Due to the power limitation, providing electrical power to WSNs often becomes very challenging. Overcome these issues, we have focused on powering up the sensor devices by alternative renewable energy sources such as solar energy along with rechargeable batteries. Also, using different techniques for energy saving is one of the essential tasks in WSNs. Many efforts have been put to reduce the energy consumption of the hardware, software, communication protocols an applications. However, energy consumption still cannot be brought down to the desired level. Therefore, we have presented a renewable-harvesting energy approach for solving the power consumption problem of the WSNs and the utilization of renewable (solar) energy to enhance the lifespan of the WSNs in environmental applications. In th？s study, we have also proposed a new renewable powered energy harvesting model for the rapid prototyping of any WSN. We have found that these approaches may play a critical role in increasing the lifespan of a WSN
