ANTI THEFT ALERT FOR STATIONARY GADGETS USING

WIRELESS TECHNOLOGYPresented by

Under the Guidance of Ms. P. BABY SHAMILI

ABSTRACT

• Present Security systems are done with mechanical switches which initiate an alarm when a certain preset level of motion is detected.

• This project overcomes the drawbacks of present security systems.

• This project can provide the security by using MEMS sensors with the help of embedded technology.

• Now a days everyone knows what type of security we need, security is needed for all the valuable devices.

• But even after taking care we are still unsatisfied with the security. Because Robbery of the devices has been increased widely.

• So as the technology is growing we are implementing new ideas over security purpose.

POWER SUPPLY

• Step Down transformer converts high-voltage, low-current power into low-voltage, high-current power.

• Bridge Rectifier is used for converting an alternating current into a direct current.

• The output of the rectifier pulsating in nature. The unwanted ripple components are removed by placing filter circuit at the output of the rectifier.

• The Voltage Regulator is used to keep the output voltage constant at the desired value.

GSM (Global System for Mobile communication)

• GSM is a digital mobile telephone system.

• The GSM module is communicate the microcontroller with

mobile phones through UART.

• GSM modem interfacing with microcontroller for SMS

control of industrial equipment.

LCD (Liquid Crystal Display)

• LCD is a flat panel display, electronic visual display that

uses the light modulation properties of liquid crystals.

• Liquid crystals do not emit light directly.

• LCDs are available to display arbitrary images or fixed

images which can be displayed or hidden.

BUZZER

• Piezo Electric buzzers are Solid state devices that produce

an Audible signal when powered.

• They are basically made up of piezo crystal.

• A simple oscillator circuit is used to make these signals

audible.

• RESET is an active High input When RESET is set to

High, 8051 goes back to the power on state.

• The 8051 is reset by holding the RST high for at least

two machine cycles.

DC MOTOR

• DC motor is an electrical machine which converts

direct current (electrical energy) into mechanical

energy.

• We use this DC motor in this project for checking the

Direct current.

PROPOSED METHOD

• If the theft is not done then the fan rotates continuously. It is the

indication of the power supply.

• When the MEMS sensor direction is changed then the fan is OFF

and the buzzer will ON.

• At that time message will be send to user mobile by the GSM

module and GPS module.

RESULT

RESULT FROM GPS & GSM

APPLICATIONS

• Apartments.

• Tollgates.

• Industries & Companies.

• Security places.

• Museums.

• Jewelry Shops.

ADVANTAGES

•Safe & secure.

•Easy to use.

•Reduce the Theft.

•Reduce the Man Power.

•Theft can caught easily.

DISADVANTAGES

• If we are not having the signal, then the

information will not be sent.

• The kit must be in the network coverage area.

CONCLUSION

• By using this anti theft, robberies of the valuable

devices can overcome, the theft can be caught easily.

• With the development of sensor technology, MEMS

sensors in the form will be varied, through the

extensive application of electronic technology to

achieve high overall performance further.

FUTURE SCOPE

• The future scope of our project is that a new anti-theft sensor system

is being developed at the advanced institute of industrial technology.

• Presently only SMS feature is available, we can include the call

feature for case of operation.

• Microphone could be interfaced to the GSM/GPS module so that

during theft activity voice call could be established with the owned.
