technology and the application requirement. electronic alarm system [7]. burglar alarms, duress alarms, industrial alarms, speed limit alarms, and anti-theft car alarms. with a bell at the output or a siren so as to alert the owner of what so ever is to be secured. ? When the two LDRs are in dark, there is no movement in the panel. ? Now place a torch in front of the left LDR. Panels slowly move towards its left. ? Now move light from left to right. You can observe the panel moving slowly with the torch towards right. No security system is complete without lasers. So in this project I am going to show you how to build a laser tripwire alarm from a laser pointr, a couple of mirrors, and a few dollars of electrical parts. With this you can cover an entire house with an array of light beams. If any one of them is 2012). This project is an attempt to create a simple intruder alarm system, which detects movement and sound levels being activated by either human voice or motion. It will start with designing the PIR and Microphone circuits, followed by choosing an appropriate amplification and filtering stages. Then, it is going to cover some methods The burglar alarm switch is a little different from the buzzer switch that you made by disconnecting and connecting the wire at the beginning of this lesson. Now you want a switch that works easily and more quickly, without you having to make and break the connection with your hands. Electronic Circuit Schematics. Note that all these links are external and we cannot provide support on the circuits or offer any guarantees to their accuracy. Some circuits would be illegal to operate in most countries and others are dangerous to construct and should not be attempted by the inexperienced. Unless you are using extremely precise instruments and control/amplifier circuits, you will not want it to be so sensitive. There are plenty of things that will influence the input like humidity, temperature, and other factors. You want it to set off an alarm if there is a significant change, like a person walking in front of the sensor. Super sensitive intruder alarm block diagram Fig. 1: Super Sensitive Intruder Alarm Circuit Diagram C. can be adjusted by the value of the resistors R1, R2 and capacitor C3. Luke, T. W. (2001).
