  • Abstract:
  • This paper presents the design and development of a "Touch Released Alarm System," The system is designed to produce an alarm at any instance when a physical touch of an external probe with an object is deleted. Circuit diagram includes 555 timer integrated circuit, isolated BJT transistor (BC547), LED and buzzer for visible and audible alarm respectively, together with 9V battery. For illustration, if the object such as watch or chain is detached from the exterior probe, the circuit switches on the LED flashing and the buzzer sounding. The stable time configuration upon triggering of the 555 timer IC is that the timer IC is connected in monostable mode and the BC547 is an enable switch to the output devices which are the LEDs in this circuit. But it is very instructive to be applied in various security products like theft prevention and protection of other valuables. The paper also directs the description of the circuit with its functional aspects, and it also outlines the outcomes of the circuit as well as the practicability of applying the system in comprehensive, cost-effective design.
