Future scope

In this project, the data can be transmitted to and

received from remote Zigbee communication device.

Data Security is primary concern for every

communication system.

In this present days in every rural areas developed but in

the urban areas like hilly areas there is major problem

facing.so to modify that type of problems we are

introducing this project.

In this project we are using zigbee technology.

It is used for wireless communication.

Created for control and sensor network.

Zigbee standard for IEEE 802.15.4.

Control of lights, switches, thermostats,

appliances, etc.

Zigbee was designed to provide high data

throughput in applications where the duty

cycle is low and low power consumption is an

important consideration

Home Automation Still on Horizon

Street light are powered by solar energy. Sensors

senses the data, collect the information and sends

to ARM 7.

ARM 7 controls the signal and runs the software

to analyze the system.

Light sensor gets activated if light

illumination is achieved less than fixed

threshold to switch the lights ON, else OFF.

Now, Zigbee device (at transmission side) is

ready to receive information from streetlight

and communicate with Zigbee device (at

receiver side), then sends to terminal via USB

cable.

Zigbee device communicates point-to-point to

detect the faulty lights in the system.

By using this automatic system for street light

controlling.

We can reduce energy consumption because

the manually operated street lights are not

switched properly even sun light comes.

And also not switched on earlier before sun

set.

Solar street lighting s/m is an ideal lighting s/m

for roads, yards, residential colonies,

townships, hospitals, educational institutions

& rural areas.

This system is an ideal application for campus

and village street lighting.

This s/m is provided with battery storage

backup sufficient to operate the light for 10-

11 hours daily.

FUTURE SCOPE:

implemented this intelligent system we

reduce the maintenance cost and power thefts

of the system.

Controlling the traffic signal lights.
