The deployment of Wireless Sensor Network (WSN) for autonomous long-term monitoring of the environment has enabled applications in many diverse areas. However, WSN motes are typically powered by small batteries, which are finite energy sources and normally need periodic maintenance. Therefore, energy harvesting for WSN is a very promising solution for perpetual operations. In this paper, a solar-assisted system (SAS) for WSN is proposed. It is equipped with energy storage system to ensure uncorrupted power supply as well as a battery protection circuit to prolong the lifespan. In conclusion, WSN with SAS will have continuous and maintenance-free more operating time compared to conventional WSN.
