Security alarm
- 1. Welcome To Our Presentation Group Member: Name: ID: • Md. Sujon Bab 15207019 • Md. Enamul Haque 15207060 • Shakhawat hossian 13207125 EEE 1317
- 3. EEE 1317
- 4. Instruments: • For circuit: 1. Vero board. 2. Jumper wire. 3. Laser diode 12v. 4. Light dependent resistor(LDR). 5. Arduino UNO. 6.Resistor. 7.Veriable resistor. 8. Soldering Iron. 9. 12v buzzer. 10. 5v and 12v power supply. 11.LED. 12. IC LM324, ULN2003.
- 5. Why we use? Security is a most important factor today. Technology develops day by day in the world. The crime gang also improves their technology toper form their operation. So technology of security should be modern with time to protect the crime works. We decide to make a security project as our project. In this project we have used laser light to cover a large area. EEE 1317
- 6. Laser and LED: We know laser light goes through long distance without scattering effect. It’s also visible only at source and incident point, otherwise invisible. These two properties help us to build up a modern security system, which may name as “laser security”. EEE 1317
- 7. Working: When any personor object crossover the laser line the security alarm will ringing and also the focus light will “on” to focus the entrance of unauthorized person. We can make a security boundary of single laser light by using mirror at every corner for reflection. EEE 1317
- 8. ADVANTAGES 1. Ready to use 2. Easy in construction 3. Consume less power 4. Economical and light in weight 5. Motion sensors can be added to improve security EEE 1317
- 9. Dis-advantage: • Heating effect in LDR • Lasting • Notification for any types of object EEE 1317
- 10. • This Laser Security System is very useful in high command security place • Hostel • Hospitals • Institutions • Buildings • Home security • Office and corporate security • Protection from thieves in shops, banks, houses etc. APPLICATIONS:

Editor's Notes
- Linear encoders are usually around $500 for 100 mm travel encoder, cost increases with length. Rotary encoders are relatively inexpensive – tend to be under 100 dollars No mechanical reduction between motor and load, thus servo response (bandwidth) must be faster. Includes higher encoder bandwidth and servo update rates Linear motors are not compact force generators when compared to rotary motor with transmission offering mechanical advantage. Example 3/8” diam. Ball screw produces 100 lb of thrust, while 15 lb of linear thrust typically requires 2” x 1.5” cross section. Heat management techniques such as air and water cooling options (both common, popular) have to be applied Suppose it’s traveling at 3 m/s and loses power. Without resistance, it will quickly reach end of end of system, mechanical stops. Linear encoders are usually around $500 for 100 mm travel encoder, cost increases with length.
