Remote Alarm Monitor System Based On GSM and ARM

This paper presents a remote monitor and control alarm system based on GSM and ARM. This system uses ARM-based microcontroller LPC2368 as the MCU, a smoke sensor MQ-2 to detect the harmful gas, the temperature sensor DS18B20 to monitor the temperature, the humidity sensor HS1101 to check the humidity in the room. Also we use gate magnetic switch, we fix them on the door and windows to monitor the invasion. If the householder comes back, he can enter the password through the keyboard. The microcontroller then disables the alarm from the gate magnetic switch. Once the abnormal occurs, the MCU gets the alarm signal immediately, and the system controls the camera to take photos, and send multimedia messages (MMS) to inform the alarm information.
