Abstract

Noise detector and motion sensor surveillance system has been chosen as the undergraduate project title. The project is basically to build a surveillance system that will measure the two parameters; noise and motion. Setting point to detect motion is motion that lesser than lO meter (M). This system is applied only for housing area application. Noise detection will use a condenser microphone as the input to measure the noise of the covered area while ultrasonic transducer is used for motion detector circuit. Both detector circuits will be connected to an alarm circuit, where the siren alarm and the light emitted diode (LED) will be used in this project to report the status of the system. Alarm circuit will be triggered when both or either one of the output from the detector circuit trigger the relay that connect the detection circuit with the alarm circuit. The alarm output which is an 80 speaker is capable to deliver the siren alarm of 60dB. Active Ultrasonic sensing technique will be used instead of the passive technique to make sure the detection in the covered area is completely under control. First stage of the circuit operation is to detect the circuit and then the output of the circuit will turn the relay to second stage that is the alarm circuit. Alarm circuit will produce a siren and tum on the LED which is the control console inside the house.
