harmful gases Wireless communication of the

data

INTRODUCTION

Purpose of the Project: To overcome excess

energy consumption due to street lights

in a wide area and real time monitoring of

individual street lights

What the project does to fulfill the purpose:

1. Solar energy.

2. Power LED’s .

3. Wireless transeceiver .

LITERATURE SURVEY

Communication system for street light controller

• PLC Communication System Remote controller wires and repeaters • TinyMesh Low price Low data rate – 10kbps, sufficient for application Low power consumption Reliable.

LUMINARIES

Low power discharge lamp Uses inert gas and small quantity of mercury High efficiency and economy Difficult to control the distribution of emitted light

High intensity discharge lamps Uses electric arc between tungsten electrodes High level of light over large area Costly to produce, install, purchase, repair

CONTINUED..

LED – Light emitting diode

Compact size Very high lumen output Vibration resistance no filaments No UV or IR emissions 50-90 % less energy

consumption.
