Abstract

Wireless Sensor Network (WSN) is an advanced technology that allows users to monitor the environmental or physical condition such as light intensity, temperature, pressure and many more. Generally, WSN motes are powered by two AA sized batteries. However, these batteries have a limited lifespan and need to be changed whenever their energy supply is depleted. Therefore, solutions using energy harvesting system has been proposed to overcome this problem. Nevertheless, many existing design are quite complicated. In this work, a simple and low cost solar energy harvester for WSN is developed. Solar power was chosen due to its wide availability and high power density. The solar energy harvesting circuit consists of a solar panel, rechargeable batteries and a voltage regulator. Experimental results of the harvester have shown that even a simple solar energy harvesting system is able to supply sufficient energy to ensure the WSN's continuous operation. Furthermore, the simple solar harvester design can provide a starting guide for researchers and engineers to quickly obtain a working knowledge in this exciting and emerging area.

用于无线传感器网络的简单太阳能收集器

无线传感器网络(WSN)是一种先进的技术，允许用户监测环境或物理状况，如光强度、温度、压力等。一般来说，无线传感器网络由两节AA级电池供电。然而，这些电池的寿命是有限的，当它们的能量供应耗尽时，就需要更换。因此，提出了利用能量收集系统来克服这一问题的解决方案。然而，许多现有的设计相当复杂。本文研制了一种简单、低成本的无线传感器网络太阳能采集器。选择太阳能是因为它的广泛可用性和高功率密度。太阳能收集电路由太阳能电池板、可充电电池和电压调节器组成。实验结果表明，即使是一个简单的太阳能收集系统也能提供足够的能量来保证无线传感器网络的连续运行。此外，简单的太阳能采集器设计可以为研究人员和工程师提供一个入门指南，以快速获得这个令人兴奋的新兴领域的工作知识。
