The problem faced by many institutions such as museums and banks is that of security 24 hours a day. Security guards are expensive and thieves have learned to evade conventional security devices such as infrared, thermal sensors, etc. The use of SONAR in a security system, as used in our project, is a novel idea and, difficult, if not impossible, to evade. Infrared rays have the disadvantages of covering only a limited area in a room And to cover an entire room requires many of these beams. This makes this technology very costly. Nor is it infallible and can be evaded by experts as has been so demonstrated in so many Hollywood movies. Temperature sensors can also be circumvented as they can be very sensitive and risk of false alarm shots due to changes in ambient temperature or less sensitive with the risk of allowing evasion. The use of SONAR offers us many advantages. It is almost infallible, albeit at the expense of being extremely sensitive to the point that the only way to avoid triggering the alarm is to make sure that the room you are covering is free of any movement. In this project we have designed and developed a unique security system that uses the capabilities of the microcontroller and a special purpose SONAR module. It is also extremely cost-effective when compared to similar systems currently in use.
