In this paper, the authors present 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, they can enter the password through the keyboard. The microcontroller then disables the alarm from the gate magnetic switch.
