Laser Light Activated Alarm

Project Proposal (Physics)Page Title: Laser Light Activated Alarm Submitted in partial fulfillment of the requirements in Research IVResearcher: Kimberly Joyce Ruiz Marcelo H. Del Pilar National Highschool, Malolos City of BulacanSource: Aldrin D. Abalos Date to be pass: July, 2013Reasearch Teacher: Mrs. Norma Lyn GarciaSignificance:This study aimed to develop a laser detector, which is able to detect unexpected visitor to prevent safety on every household. The laser light activated alarm has three main parts: a) laser, b) mirror, c) light activated alarm. This device has been developed to construct a reliable protection system.The study compares the difference of laser light activated alarm to the other commercial detector.There were several test of effectiveness of the device in terms of its ability to warn owners with the loudness of sound, amount of the energy used and percent of accuracy. The cost of the device was also considered for to prove the acceptability of the device.The device was developed to use a light activated alarm which has detecting diode or the photocell, which turns the device on when the photocell (sensor) detects light.The experiment prove that the Laser Light Activated Alarm produces the competitive sound intensity of 90 -100 dB and the cost of energy consumed of P 2.07 an hour. The commercial cost of P 1,000 was proven to have a lower commercial price than the other two commercial detectors. The ideal laser position was traced to complete the whole operation. Data of different commercial alarms were gathered to be compared to the newly developed Laser light Activated Alarm. It was made from the cheapest material, which performs its tasks better than the commercial detection alarms with the same concept.The Laser Light Activated Alarm was proven to be convertible enough to fit on any sizes of
