1. Intelligent wireless street lighting system
Abstract
Lighting systems, particularly within the public sector, are still designed per the previous
standards of reliability and that they don't usually profit of latest technological developments.
Use of renewable energy sources instead of typical power sources, therefore taking care of the
environment is another advantage of this system. In this paper a wireless street lighting system is
developed. It consists of set of sensors to detect the presence of humans and checking for the
intensity of light and transmitting the light in wireless.
Existing System:
The existing system is based on either LDR or checking for the evening time by using
RTC. In this method the remote monitoring and controlling is not there. Hence we go for a new
system.
Proposed System:
In this new system the system with LDR sensor, PIR sensor, GPS and Zigbee is used to
intimate the status of humans use, light intensity and street light ON/OFF status to the EB section
to avoid wastage of energy by glowing street lights in unwanted areas. The whole system is
operated by using artificial energy source called solar and with battery backup. The PIR and
LDR sensors sense the persons and light intensity of a particular place and transmits the data in
wireless to the EB section with its GPS section. Depend upon the data received the controller
will turn ON/OFF the street light in wireless communication.
