DESIGN OF WIRELESS SENSOR NODE FOR ENVIRONMENTAL MONITORING USING SOLAR CELL

Abstract

Harvesting solar energy and utilizing it for wireless sensor node (WSN) network is a creative idea.
Due to advancements in renewable energy harvesting technologies, the traditional battery powered WSN’s
are replaced by efficient renewable energy harvesting devices. In this paper lightweight mashup middleware
architecture is proposed which provides monitoring the remote area and control automation for physical
sensor devices. In this proposed system, the energy is harvested from solar panels which is connected to
low-power energy harvester circuits and batteries that are rechargeable which provide a loom to make the
WSN nodes entirely self-powered with an infinite lifetime network. The LoRa Low power WSN (LPWSN)
provides a cluster tree which is assigned for monitoring environment, and also proposes an initiative for
Open Service Gateway for uniform devices access framework. By utilising IoT based visualization
technology, theLoRa technology creates the GUI of different physical sensor devices, which permits the
sensors to merge with various resources easily. Performance measurement and also analysis is important
though the illustration of safety monitoring and control automation scenarios are done. This experiment
proved that lightweight mashup middleware is cost efficient to create safe monitoring of environment and
automation of applications by using solar renewable energy harvesting.
