GSM Based Anti-theft Alarm With On/Off System
An anti-theft system is any device or method used to prevent or deter the unauthorized appropriation of items considered valuable. Theft is one of the most common and oldest criminal behaviors. Where the ownership of a physical possession can be altered without the rightful owner's consent, theft prevention has been introduced to assert the ownership whenever the rightful owner is physically absent. Anti-theft systems have been around since individuals began stealing other people's property and have evolved accordingly to thwart increasingly complex methods of theft. From the invention of the first lock and key to the introduction of RFID tags and biometric identification, Anti-theft systems have evolved to match the introduction of new inventions to society and the resulting theft of them by others.
1- Give Power Supply to the Modem by which the circuit also gets the power supply.
2- Wait for the modem to be configured.
3- If everything is ok it will send you a message “GSM controlled device is activated”.
4- Now three features are provided to this project i.e. Collision detection, Gate alert and Facility to start stop your motor which is for simulation of the ignition system of your car.
5- When you will open the wire on PCB it will alert you by message “Someone tried to open your door”.
6- When you will push the button it will alert you by message“ Collision detected, help required”.
7- To start your motor send a message to the number you provided to the modem “35791 ON” it will start the motor and will send you an acknowledgment “Vehicle is started”.
8- To stop your motor send a message to the number you provided to the modem “35791 OFF” it will start the motor and will send you an acknowledgment “Vehicle is stopped”.
9- After completion of project disconnect the power supply.
