GSM based Door Access Security System

GSM based Door Access Security System

Project Cost: 8,900

Project Code: 1646

Description of the project:

GSM based Door Access Security System has main application in security systems and it can be used in Industries, Shops, Offices and in our homes. It replaces the traditional security systems which uses key to open door. This project has keyless entry to the door. User has to send password through sms using his/her mobile. If the password is correct then Microcontroller turns on a DC motor and a Relay. Buzzer is turned on for wrong password.

    I am searching for a circuit card for use in a security system with GSM cellular connectivity via a SIM card.
    Preferred features are:
    1) low power consumption in the resting state (non-alarmed)
    2) if external power is lost until internal battery is dead and then external power is later restored the unit will return to the prior ARMED mode.
    3) wired sensors only are required and very few … only one would be okay.

    sir. My question is How actually implement this project on door? actually supply required for door open and close,which type of door is used for this project?

    • Microtronics Technologies

      Hi More Ashwini, this project does not open the actual door. It opens the latch connected to the door. Or it can be used to actuate the magnetic locks connected to the door. We have to push the door by our hand to open it. This system just unlocks the door.

    Hey! how this motor rotates for opening the door while it turns on?
