Intelligent lighting control and energy management
system is a perfect solution for energy saving especially
in public lighting management.
It realizes remote on/off and dimming of lights, which
can save energy by 40%, save lights maintenance costs
by 50%, and prolong lamp life by 25%.

• GSM is a standard developed by the ETSI to describe
protocols for second generation(2G) digital cellular networks
used by phones.
• GSM Modem can accept any GSM network operator SIM card
and act just like a mobile phone with its own unique phone
number. Advantage of using this modem will be that you can
use its RS232 port to communicate and develop embedded
• The modem can either be connected to PC serial port directly
or to any microcontroller. It can be used to send and receive

In this paper Intelligent street lighting system is
described that integrates new technologies offering
ease of maintenance and energy savings.
The proposed system is appropriate for street lighting
in remote as well as urban areas where traffic is low at
Along with energy saving it also tackles with the
problem of power theft. It is capable of taking
corrective actions in case of unprecedented events of
