All about burglar alarms and how it works?
The basic principle is photo electric emission. When UV rays fall on certain substances, then electrons will be emitted. So in case of burglar alarm, some invisible such as ultra violet (UV) rays are made fall on the a particular point where a photo cell is fixed. in front of the jewel stored room. If the radiations fall continuously there will be a steady emission and so a current is steadily flowing. If any one goes nearby by the room breaking these radiations falling on the photo cells, then a break in the continuous flow of current would activate another circuit consisting of an alarm. So the alarm functions henever any burglar comes near by the cash and jewel stored up room.
