ABSTRACT:
Much technological advancement has
occurred in the last couple of decades, and
even greater innovations seem to be at the
horizon. Many large and influential
companies are built on the platform of
technological tools and most of the
advancements have been in the field of
Electronics. But every device has an
operational constrain. It cannot work
continuously. It should be given rest for
some amount of time, in order to maintain
its efficiency. Also with the advent of new
technologies a lot of power is wasted. For
example due to overheating of coil in
machines, the efficiency and the life time of
the machine is affected. Another example
is that, many people forget to switch off the
mobile phones at the right time, due to
which the bulging of batteries occurs and
power is also being wasted. Thus the main
objective of our paper is to conserve the
electrical energy and to maintain the
efficiency of the device. Our paper deals in
controlling the operation of any Electrical
devices based on a programmed schedule
using a Microcontroller. Thus, the user
can set the ON time and OFF time for any
device. The device will work for the given
ON time and will be automatically
switched OFF, for the given OFF time.
Then, it will again resume its operation
after the OFF time and the cycle repeats
itself. When there is a fault in the normal
working of the device, the sensor detects it.
Then the user can turn off the device by
gaining control over it by just switching
over the SPTT switch. Our paper uses a
programmable Digital Timer, based on a
Microcontroller that can be programmed
to schedule the ON and OFF operation of
an Electrical appliance. The appliance is
controlled through a Relay switch. This
Timer switch allows the user to set both
ON and OFF Time. Our project uses a
LCD with 4 push buttons to interact with
the user. Application of our project ranges
from small household devices to large
industrial based machines. Thus our paper
eliminates the work of monitoring the
devices as the device regulates its ON and
OFF operation by itself. Also in case of
emergency or need, by just switching over
the SPTT switch the user can turn off the
device through its normal switching
operation. Our project mainly aims at
conserving energy by efficient use of
Electronic and Electrical devices.
1. OBJECTIVE:
The main objective of our paper is
I. To conserve the Electrical Energy.
II. To increase the life time and the efficiency of Electrical devices.
2. KEY TERMINOLOGIES:
Single Pole Triple Throw (SPTT) Switch
Bridge Rectifier
Regulator
Microcontroller
Real Time Clock
Crystal oscillator.
3. WORKING:
The working can be explained in 2
parts,
Automated Energy Saver
Switching Action
3.1. Working of Automated
Energy Saver:
The machine to be monitored is
connected to the automated energy
saver. The Automated Energy Saver
acts as the power supply for the
machine. The ON time and the OFF
time can be set in Automated Energy
Saver. The machine works for the
given ON time and automatically
switches OFF during the OFF time.
There can be a sequence of 50 ON and
OFF time. Thus it eliminates the work
of external monitoring. The working is
described below,
Initially a 9v ac supply is given to
the bridge rectifier.
It converts the 9v AC into DC.
Then the regulator converts the 9v
DC to 5v DC.
This power is used for the
operation of the remaining part of
the circuit which primarily consists
of Microcontroller and the seven
segment display.
The microcontroller is a 40 pin IC
(AT89C52). Microcontroller
controls the operation of the device
with the help of the hexcode burnt
in it.
The output is given in the pin 17.
The display segment consists of 6
separate seven segment displays
(LT542) and 4 LED’s.
The output from pin 32, 2, and 39
of AT89C52 is taken as (Display
Segment) DS0 to DS6 output,
which is used to select and provide
the necessary amplification
required to power the 6 separate
display segments in the display
panel.
In the segment display the segment
that is to be lit, in a single display
is represented or controlled from
pin 21 to pin 28 of AT89C52, ie
(SS0 to SS6) outputs.
Thus the device works for the given
On time and switches itself OFF in the
specified time.

Energy Saver
3.2. SWITCHING ACTION:
The switching part is introduced in
order to employ safety measures.
A sensor is attached to the coil of
the machine.
When the temperature goes beyond
the particular limit, sensor sends a
signal that makes the machine to go
to ground state (Open circuit).
Also when the user wants to gain
control over the machine at
emergency situations or for any
other purpose the SPTT switch
must be pulled down to make it
work like the normal switch.

4. APPLICATIONS:
Application of our project ranges from
small household devices to large
industrial based machines. Every
Electrical and Electronic devices needs
to be monitored well. Also rest is the
fundamental need for it. But our paper
mainly focuses on large scale
organizations where machines need to
be operated in shifts. Thus, this paper
when implemented will be a great use
for the electrically controlled devices.
5. CONCLUSION:
Thus our paper eliminates the work of
monitoring the devices as the device
regulates its ON and OFF operation by
itself. Thus the efficiency of the device
is increased and the lifetime is
prolonged. Also with the help of the
sensor emergency situation can be
tackled. Another main advantage of
our paper is that, the machine can be
operated under the normal switching
action too. Thus our project aims at
conserving energy by efficient use of
Electronic and Electrical devices.
