home security

Protection system provided as a Gas detector and fire detector are connecting to alarm sound and LEDs; which are represent the alarm audio and visual alarm. The gas detector and fire detector linked to the GSM the idea of GSM is transfer a message (SMS) to my phone and the fire station. ** For more security we are able to avoid burns resulting from gas leak. I would like to turn off the home electricity except the security devises because movement sensor , it used for more security if someone unwelcome at home during the night or when the hose resident is far away from the home. The movement sensor will monitor and lurk the home from anybody is not allowed to be at home. It will be transferred a message by the GSM as soon as the sensor turn on. To keep the house in safe with security system IR sensor will be used in windows at home to protract the house from thieves. Once the thief entered the alarm audio and visual alarm are switched on. GSM will be transmitted a message (SMS) to owners and the police. This system has a fundamental point which is Keypad. The door is controlled electrically using keypad and GSM, the door opens and closes (manually) through a secret number enters in the keypad or wirelessly through GSM (transfer SMS ) The microcontroller STM32 MCU Nucleo is interfaced with my component.
