Home door and windows monitoring system: article / Muhammad Zulfadhli Drahman

Intrusion always happen if the door or windows of the house are left open. Apparently there is no warning system to monitor the door and windows state. The situation became more critical if there is a child in the house that tends to wander off to the street. It becomes worst especially at night or when the owner is on vacation where there is risk of breaking in. This paper presents the development of the Home Door and Windows Monitoring System to monitor the state of the door and windows by using Short Message Service (SMS) to interact between the system and the user. The system uses Arduino UNO to manage the operation, the GSM Shield to receive command and send message through SMS and the magnetic switch to trigger the system operation. The push button is use to gain access to enter or leave the house. The system is password protected and it can be set into three different operating modes. The Asking Mode where the user can ask the system about the state of the door and windows, the Notify Mode where the user can be notify about the state of the door without being ask, and the Secure Mode where the user can be alert if the door and windows are open. The prototype have been tested and functioned properly as to remind the user of the state of the door and windows of the house.
