Introduction

Its about a simple circuit to alarm you when somebody tries to theft your luggage.

Abstract

While traveling by a train or bus, we generally lock our luggage using a chain-and-lock arrangement.

But, still we are under tension, apprehending that somebody may cut the chain and steal our luggage.

Circuit diagram

Explanation on circuit

In the above circuit diagram the main IC used is ICX UM3561.

UM3561 is an excellent ROM IC that can generate Multi siren tones.

This 8 pin low power IC can work down to 2.4 volts.

Three transistors are used. T1 enables supply to the sound generator chip

Explanation on circuit

Two points on the circuit diagram are named “A” & “B” are connected to the chain.

The chain is connected to the luggage.

Working

When somebody tries to cut the chain, Transistor T1 enables supply to the sound generator chip.

Positive supply to the alarm circuit is given through the transistor T1 with the ground.

Advantage

Since the power consumption is minimum in the alarm circuit it can be used for the hundreds of hours travel.

Since, this is a simple circuit we can use this wherever we need to prevent.

Application

Used in the traveling through the busses and trains.

Useful for the people traveling with huge amount and highly valuable things.

Future work

If we implement this circuit in house door lock system, we can prevent our belongings from theft.

Conclusion

We can prevent our belongings using this simple circuit.
