Abstract— 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. Gate magnetic switch is fixed 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 magneticswitch. Once the abnormality occurs, the MCU gets the alarm signal immediately, and the system controls the camera to take photos and send multimedia messages to inform the alarm information.
