Title : Infrared Motion Detector For Home Security (Video)

Objective : To show how the system function

Content / Procedure :

• First step show how to ON and OFF the security system.Infrared Motion detector also activate when the security ON.

• Second step show that the buzzer will sound when the door open without password.At the same time pepper gas spray also activate.

• Third step show that when enter wrong password three times, the buzzer will sound and at the same time pepper gas spray will activate.

For more detail,I have explain how the system work in my post on week 22.

Title : Home Design Prototype

Objective : To design the house prototype used to install the security system.

Contents / Procedure : 

List of material use to design the home prototype :

1. Perspex

2. wood block

3. PCB stand

4. cellophane tape

5. Perspex glue

6. Perspex cutter

Result /Analysis :

Figure below show the home prototype design :

Title : Output of the system (circuit output)

Objective : To explain how the system works

Contents / procedure :

In this system there is a keypad to enter the password (input stage) and LCD to display the output (output stage).To activate the security system,firstly press button 'A' at keypad to set the password.Then press button 'B' to re-enter the password that have been set.When the security is activate, check the motion detector.Buzzer will on to indicate that the motion detector is function.Buzzer will off when it doesn't detect motion within the range.This motion detector and buzzer can replace the bell because if there is people outside the house the buzzer will sound.This system not only can be used when we are not at home, but also when we are at home. If there is stranger who tried to get into the house without using the password , the siren will sound when the magnetic lock is open.At the same time pepper gas spray will work.Siren will also sound if three times enter the wrong password.To reset the system when the alarm is activate, press button 'B' at keypad and enter the password that have been set for reset the system.This password is not the same password used to open the magnetic lock.So it is important to remember this password.

Result / analysis :

Figure : keypad

Keypad : to set the password.

1. LCD display the 'Home Security System'

Figure : LCD display

2. After that, press button 'A' at keypad, and LCD will display set password 1.After set the password, press button 'B' and again re-enter the password to activate the system ( LCD will display security ON).

3.When the security is activate, siren will on when there is motion detect by motion detector.Siren will only sound when there is motion within the range that the motion detector can detect.

4. If the magnetic lock is open without using password, buzzer will sound.The pepper gas spray also function at the same time.

5. To reset the system, press the button 'B' and enter the password that have been set to reset the system.

Conclusion : This home security system works well.
