Invisible beam property guard alarm system (ISP2) / Edward Tedong

An alarm system is a device for guarding against unauthorised intrusion of guarded areas. It detects people, animals, vehicles, paths or wherever potential traffic or unauthorised trespassing may take place. It can be made to detect either existing or entering traffic. Lights, sunlight, leaves or other potential false triggers do not bother it. The link use between transmitter and receiver is infrared energy pulses because of its invisibility from detected by potential intruder. The infrared energy pulses that present between the transmitter and receiver acts as beam sensor that guarded the areas. In this project report, hardware of alarm system was constructed. The simulation and experimental results proved the successfully of hardware construction.
