Scene 1

. . ORIGINATION OF THE IDEA. Our initial idea for this model came to us during the
pandemic that we have been going through since. 

Scene 2

Our initial idea for this model came to us during the
pandemic that we have been going through since

2020. When we began offline school, our school
guards took the necessary COVID precautionary

temperature at the gate. During the exams, we

witnessed a student, who was so busy studying that
she forgot to wear her mask. After being told to do

so by the guard, she was offended and started

arguing with him. We realised that we could come
up with a model that would prevent such conflicts.

Under the guidance of our physics teacher, Mr.

Neeraj Pant, we were able to come up with a

. . In everyday life, people with busy lives tend to forget to wear their masks. Sometimes, people that refuse to wear masks because of personal choices get into conflicts with people that ask them to do so.. 

Scene 3

In everyday life, people with busy 
lives tend to forget to wear their 
masks. Sometimes, people that 
refuse to wear masks because of 
personal choices get into conflicts 
with people that ask them to do so.

We thought that this model would 
remind people to wear their masks at 
all times, to ensure their safety and 
that of the people around them

. . DESCRIPTION OF THE COMPONENTS. TRANSISTOR
Transistors are
commonly used in
digital circuits as
electronic switches
which can be either in
an "on" or "off" state.

REGULATORS
The purpose of the
regulators is to keep
the voltage  in a
circuit and the
volume of the
system relatively
close to a desired
value.

AUDIO
AMPLIFIER KIT
The goal of audio
amplifiers is to
reproduce input
audio signals at
sound-producing
output elements,
with desired volume
and power levels—
faithfully, efficiently,
and at low distortion

RECORDER
KIT
A voice recorder
captures sound,
converting it into an
audio file that can
be conveniently
played through the
speaker

TRANSFORMER
Transformer refers to
a device which can
change the tone or
pitch or add
distortion to the
user's voice to ensure  
accuracy in the
working of the 
 announcement
system

. . RECTIFIER
A rectifier is an
electrical device that
converts AC to the DC
current in a circuit.
TIMER
The timer is used to
measure specific
time intervals for
the announcement
of the voice
recording in the
system.

PIR MOTION
SENSOR 
PIR sensor is one of
the main
components in our
model and is  used
for  thermal
sensing
applications and
to detect the
motion of the
people passing
through in order to
make the
announcement
happen

RELAY
Relays are electric
switches that use
electromagnetism to
convert small
electrical stimuli into
larger currents

SPEAKER
speaker is the main
component of our
model and it is used
for the
announcement of
the voice recorded 
 through the
recorder kit in order
to make the people
aware of wearing
their masks at all
times

Scene 10

Our model can be installed in schools so that the students
moving in the corridors and classes can be aware of wearing

their masks for their safety and that of the others at all

In supermarkets and malls where people might forget to wear

their masks as they are busy shopping, Our model will be

helpful to remind them to wear their masks so that they can

Hospitals usually have a rush of people at all times which can
form a crowd of people. In their stressful hours, people tend to
forget to wear their masks. Our model will make sure to remind
them that as much they care about their loved ones, they should

also care about themselves and wear their masks

Our model is helpful for workaholics as well. We all know once we

are focused on the work we tend to forget other stuff. Our

announcement system when installed in  government offices, the
people there can focus both on their work and keeping themselves
