Transcript of INTRUSION ALARM via PASSIVE INFRARED SENSOR

Introduction
The term "Passive Infrared", or "PIR", is commonly assigned to the technology of motion detectors used to detect people by sensing the thermal infrared radiation emitted by the human body. PIR sensors offer wide variety of applications for it can be used in schools, shopping malls, hospitals, factories and even at home.

Abstract
Advantages of PIR sensors to other sensors:
• PIR sensors are small, inexpensive, low power, rugged, have a wide lens range, are easy to interface with, and are easy to use.
• They don’t wear out.
• They are also fairly complex.
• the system is single ended.
• The system is passive and the detectors consume less power.
• The detectors complement cameras and they are small in size.

Methodology:
Gathering the parts of the device
Circuit construction
Programming
Testing

Robbery, with 26,988 incidents last 2012, is one the top three commonly committed crimes according to the Philippine National Police Directorate for Investigation and Detective Management. Currently, one of the most effective way of preventing theft and robbery is the use of alarms. This research paper aims to discuss the use of PIR as a motion sensor and measure the device’s effectiveness and level of acceptance.


The materials mainly used are the PIR sensor, Arduino microcontroller, and piezzo-electric buzzer. The device is programmed with the Arduino software. After prototyping, the device was tested and used by the respondents who are home owners and security guards. In terms of usefulness, the mean of 4.86 and 4.74 in a scale of 0-5 was given by home owners and security guards respectively. The researchers concluded that the device is extremely accepted by the respondents and useful as an intruder alarm.
