    This circuit utilizing a 555 timer IC can be used as an alarm system to prevent the theft of your luggage, burglars breaking into your house etc. The alarm goes ON when a push pull switch, on which luggage is placed releases.

    The circuit is straightforward. It uses a 555 IC wired as an astable multivibrator to produce a tone of frequency of about 1kHz which gives out a shrill noise to scare away the burglar.
    Four small push buttons are used as sensor to tell the presence of luggage. You can even use single strands of copper form a power cable.

    The circuit operates on a wide range of voltages from 5V to 15V. The speaker and the circuit could be housed inside a tin can with holes drilled on the speaker side for the sound to come out.

    Q1. Where we can use this project?
    Ans1. We can use this project in house on door lock and other places from preventing any intruder to come in your premises. It is very useful while placing or putting our luggage or any other important item in trains, buses, clock rooms, station and other places.

    Q2. What else we can in place of buttons?
    Ans2. We can use wire or any piezoelectric material which will sense the load.

    Q3.  What is the mode/configuration of 555 timer IC used?
    Ans3. The 555 timer IC is used in an astable multivibrator mode.  

    Q4. What is the role of 555 timer IC in this project?
     Ans4. An Astable Multivibrator is an oscillator circuit that continuously produces rectangular wave without the aid of external triggering. So when circuit breaks due to external disturbance alarm turns on.

    Q5. What is the disadvantage of this project?
    Ans5. The sound of alarm is very low so it will not help if the person is far away from the system. It can be enhanced by interfacing appropriate component
