The advanced security system for the home has changed to the modern security system in our day to day. Security systems are protected in the home of the thief, dangerous incidents in our home environment. The home security system starts by keeping the security of things. Home security has to start the home owner and take care of the home. The best way to protect the home is by installing the home security system. There are two different types of security system, ie wiring and wireless security system. Today, most of them are using the wireless security system.
It is easy to use and protected by the unknown person. The values of the wireless system are the camera, motion detector sensor, alarm sound with the help of this the home is insured with its every one of its functions. Home security systems are often used by the monitor sensor and motion sensor and are placed in unfamiliar locations.
Home security system can be achieved by adopting essential controllers to control household appliances that detect different variables using suitable sensors. This security system involves security hardware such as property, locks, doors, lighting, alarm systems and security cameras. The main feature of this system is a sensory system that collects parameter information such as fire, temperature, gas, human presence, etc., and sends information related to the Microcontroller.
The microcontroller used in this system is preprogrammed so that when the parameters cross their preset limits, it sends the control signals to different control devices like motors, relays and buzzer devices. The proposed system can be implemented using the following functional blocks.
Home security system with 8051 microcontroller
There are three basic modules in the home security systems given below. The first module is IR transmitter and receiver module that is used for doors for safety purpose at night and when the person goes outside. If an unauthorized person is introduced into the home, the IR sensors are activated with the buzzer. Then the buzzer produces the beep. The second stage of the module is an LPG gas sensor.
It is used to detect gas leakage. If the gas is detected by the sensor then the buzzer activates and produces the sound. The third module is the door opened with the help of a password using the keyboard. If the unauthorized person enters the three wrong passwords accordingly. Then the data of all the modules are sent to the computer through the serial ports. The following block diagram shows the home security system using the 8051 microcontroller.
