PURPOSE
develop a system based on embedded micro controller, which is used for home automation and security and also a detection of fire and gas leakage.
This can be used for security as well as better management for electricity and safety
DESCRIPTION
The basic idea of this project is to develop a model in which, a main gate having digital counter arrangement is there which counts the number of person’s entry or exit.
As well as another sensor with digital locking with password is provided for safety of the locker.
If any person breaks the lock without giving the password suddenly a alarm will be raised as well as a message will be sent to a specific number.
Also the total details about the counter (Persons entry and exit) can be gained just by sending a SMS “STATUS” to a specific number.
POWER SUPPLY UNIT:
We need a 5V dc supply as operating voltage for the microcontroller unit and other devices
the power supply unit is constructed to convert the 230V ac supply to the required dc (5V).
SERIAL COMMUNICATION:
Two serial ports are required for interfacing GSM modem
The modules are interfaced with the serial port of the microcontroller.
