microcontroller 8051 security alarm based system circuits GSM based Home security system hidden cameras

GSM based home security system project using microcontroller 8051.

This technical post is actually a tutorial on how to interface gps or gsm module with a microcontroller for different applications like security, control and monitoring, or home appliances control etc.

 Main aim of this project is to provide sms based tracking of different locations in the home while you are not at home.This project can also be used to monitor the different signals conditions of the machines in factory or industry. A GPS module will be installed in the home which will transmit the status of different doors continuously after short intervals or when the status of any signal is changed. Location will be sent as a sms through gsm network. These messages will be received by another GSM module situated at some remote location. The purpose of this project is to monitor and control electrical devices (Analog and Digital) remotely using GSM modem/phone. The GSM modem provides the communication mechanism between the user and the microcontroller system by means of SMS messages.
User can have the condition of various signals attached at multiple electrical devices by receiving suitably formatted SMS message from the microcontroller based control system. These SMS commands are interpreted by microcontroller system and are transmitted to other remote mobile.
Function and methodoly of GSM Based Route monitoring and security system.
There are eight input devices attached to microcontroller, the input devices can be extended to 32 depending upon the need. But currently it has only eight inputs. The inputs can generated from from rad switches, IR transmitter and receiver or other magic switches. For security these should be implemented in such a way that these should be hidden. When any of the door is opened, corresponding switch is operated, microcontroller is continuously monitoring all eight switches, on finding the changed in status of the input from door, the microcontroller turns ON the security alarm for a few second. On the same time a SMS is sent to the remote mobile about the latest situation of the home security.
If no other switch is operated (door is not crossed) and door is re-closed on the alarm, then the security alarm will be OFF otherwise it will be ON repeatedly and do send SMS continuously to owner about home or office security.


The major building blocks of this gsm based project are:

1. Microcontroller based control system with regulated power supply.
2. GSM Modem/phone.
3. Digital and Analog sensors and controlled devices.
GSM based security system using microcontroller 8051

Above is the circuit diagram of home or office security system. We can see that system has TEN LEDs attached to microcontroller. These LEDs can serve two jobs. One is ofcourse indication and the second is "we can attach any external device with these signals like bulb or camera, or any suitable device using proper optocoupler and relays.
First LED is flashing led, which is an indication that the system is running smoothly. The second LED is for alarm against security problems, remaining eight LEDs can be used for controlling cameras in each room to take snaps of the person who has un-authorised access to that room.
Thus we say that this GPS based camera controlled security system for home or offices.
CODE of the GPS based camera controlled security system using microcontroller AT89s51 is written in keil C51 microvision 4.

  1. Hi,

    Could you please help me in doing a project using 8051 microcontroller which acts as a fire and a burglar alarm(using ir sensors or to detect motion)? Please do let me know soon

    Regards

  2. @ Asha
    How many sensors for fire and motion detection you want to use in your security project of home or offices using microcontroller.
    Please send me complete proposal of your project, i.e, what you have decided and presented to professors in university.
    what kind of sensors for fire you want to use?
    if nothing is decided or cleared sofar, then do not worried about it, we can make a good proposal of your project by mutual discussion , you can send me e-mail, also, my MSN ID is given on this blog.

    Thanks for reading the blog and liking the projects on it.

    I have not uploaded the project, you are asking so far.

    But iin near future i will develop a digital lock based on microcontroller 8051 and having LCD with keypad interface.

    So that you can get idea from it anf develop your own microcontroller project for digital lock control system.

    Dear Sir,

    Hi, I'm going to do my final year project total. "GPS-Assisted Car Parking System" is my title. This project is wants to let the vehicle to park in suitable place without driver. We will give the instruction to the vehicle. I will use GPS, PIC, ultrasonic sensor and so on to apply on my project. So, sir do you have any idea on this project? How to connect the GPS with the vehicle and the car park lot?

    No, I can tell you where the problem is in communication without examin the program written for microcontroller.
    So, if you want help from me on this project of interfacing GSM with microcontroller and displaying text on LCD, you should send these two things:
    1. Circuit diagram (should be designed in proteus isis and all files related to it)
    2. Code or program you have written sofar (all files related to it in zipped format).OK

    Your Project of interface GSM modem with microcontroller 8051 for security system of CARs or vehcals is a nice idea and you can develop this project very easily if you try concentrate on my post on the topics related to interface of mobile phobes with microcontrollers or control machiines through GSM modem and microcontrollers.
    You should try it my your own instead of asking me to send the circuit diagram and code.
    what i can help you is, i can guid you in your code or circuit designing where you are stuck or confused or feel problems, but to provide all ready made work to some one is not justified.

    You are doing interesting project.
    but you have not mention about which microcontroller and gsm or 3g you are using???
    ok any way, i suggest you to finalize the gsm modul and then search and study uts data sheets, there would be some commands on GSM to call a particular number from its list. this will solve you problem. if you donot find the information like above then directly contact the menufecturer of GSM maduls about this option.

      the error in commincation between mobile or modem with microcntroller with be confirmed using two different mobiles and modems any GSM type which support the circuit diagram and code listed above.
      Then e-mail me the results, after that we will conclude which is one is faulty, mobile, modem or microcontroller.

  76. Nikita Vasudeva for GSM modem with micro controllerFebruary 16, 2014 at 12:16 AM

    Sir,
    I am doing a project on home automation where in I monitor the temperature of a remote are. For that I am trying to dump my code into my NXP (P89V51RD2) micro controller to interface GSM modem with micro controller using PC and LCD . To achieve the same I am using flash magic as I don't have a programmer. A continuous error is being displayed when I start the process of dumping. It says "Unable to communicate(transmit/receive)".
    I have been using USB to Serial Converter(which consists of a DB-9 port), and I am dumping code for the first time. Now my project has come to a stand still, any help on the matter would be highly appreciate.
