Energy harvesting embedded wireless sensor system for building environment applications

摘要

For many wireless sensor networks applications,udindoor light energy is the only ambient energy source commonlyudavailable. Many advantages and constraints co-exist in thisudtechnology. However, relatively few indoor light poweredudharvesters have been presented and much research remains to beudcarried out on a variety of related design considerations andudtrade-offs. This work presents a solution using the Tyndall moteudand an indoor light powered wireless sensor node. It analysesuddesign considerations on several issues such as indoor lightudcharacteristics, solar panel component choice, maximum powerudpoint tracking, energy storage elements and the trade-offs andudchoices between them.
