HUMAN MOTION DETECTION USING PIR SENSOR
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 5, Issue 2
Abstract
The objective of this project is to develop a motion sensor alarm based working on Passive Infra-Red (PIR) sensor module. There are many sellers that manufacture the PIR sensor modules are all method most the same in function. PIR sensor detects the human movements or the IR level of human. PIR sensors can detect levels of infrared radiation. In our project, microcontroller continuously monitors the output from the sensor module function and turns a buzzer on, when it goes active. The application areas of this project are outdoor lights, Lift lobby, Multi apartment complex, common of staircases, for basement or covered parking area, shopping malls and garden lights. Certain that crystalline materials have the property to generate a surface electric charge when expose and flow of thermal infrared radiation. This phenomenon also known as pyro electricity. The presence of human body creates a sudden changes inside the IR profile of the surrounding that is sensed by the pyro electric sensor. PIR are made of the pyro electric profile sensor. When that microcontroller detects the sensor is triggered, it drives the buzzer. The sensor is working to the retriggering mode, the buzzer remains on as long as the motion is continuously sensed.
