3. An
infrared
security
alarm
system
is
based
on
the
detecBon
of
an
intrusion
caused
by
the
interrupBon
of
an
infrared
light
beam,
which
is
invisible
to
naked
eyes
and
emiEed
by
an
infrared
LED.
This
light
falls
upon
a
matched
photodiode,
which
is
in
line
of
sight
of
the
IR
LED.
In
this
project,
we
will
design
two
separate
circuits:
a
transmiEer
and
a
receiver.
The
transmiEer
circuit
emits
a
conBnuous
infrared
beam
to
the
photodiode
in
the
receiver
circuit.
We
keep
the
transmiEer
and
receiver
circuits
on
a
plane.
When
an
obstacle
comes
in
between
the
transmiEer
and
the
receiver,
the
buzzer
starts
to
beep.
Even
aMer
the
obstacle
is
removed,
the
buzzer
conBnues
to
beep,
due
to
the
feedback
system
created
using
a
relay.
