When the intensity of sound exceeds certain intensity, the alarm is
triggered and the siren begins to operate. The speaker beeps and the flasher
(light) flashes. Thus the owner of the residence is alerted when an intruder comes.

The functional block diagram includes
-MICROPHONE
-AMPLIFIER
-LATCH
-OSCILLATOR
-FLASHER
-SPEAKER

a 600O unidirectional moving coil microphone is used. LM386 CMOS operational amplifier was the main component in the amplifier. It had a gain of 200. The amplifier then passes it on to the latch section of t ....etc

The circuit illustrated here is used as Burglar alarm. LDR is kept at such a place that when thief enters our house then a shadow will fall on the LDR. A small beam of light source is also needed to supply continuous signal to LDR. For best Light source we can use Laser diode which will work for few km. For home use Infra Red LED s will be good and will be tricky to thief and works with same efficiency at night.

This circuit uses a popular timer I.C which is 555. I.C 555 is connected as comparator with pin 6 connected with positive supply, t ....etc

In the past, hardwired alarm systems are the only choice for customers who need security equipment to protect premises. Today, with rapid technology evolve, many users shift from hardwired alarm to wireless alarm. It seems home security industry is moving from hardwired to wireless, but as one of mature and stable alarm equipment, some users still favor the hard wired alarm system. In this article, we will show you some basic information about advantages and disadvantages of hardwired alarm systems.
