ABSTRACT: Now a days sensor is operated in various field for
e.g. home appliance, remote controlling in Industry, security
system for lockers. All this available in market is Led type, infra
red transmitting the pulses and receiver gets the pulses in between
the movable objectIn our project tilt sensor as a security system
for bank lockers i.e. when a door locker will move , a Tilt sensor
in system corresponding locker is automatically activated i.e. if
sensor is activated the sound will be sending to a siren . The name
"multivibrator" was initially applied to the free-running
oscillator version of the circuit because its output waveform was
rich in harmonics.There are three types of multivibrator circuit
depending on the circuit operation: astable, in which the circuit
is not stable in either state it continually switches from one
state to the other. It does not require an input such as a clock
pulse
The tilt sensor is connected to an IC 555 timer will generate
its own frequency pulses the slanting and sloping position of the
object can break the pulses and at a time siren will be
activated.
This project uses regulated 5V, 500mA power supply. 7805 three
terminal voltage regulator is used for voltage regulation. Bridge
type full wave rectifier is used to rectify the ac out put of
secondary of 230/18V step down transformer.
