Radio Transmitter Devices Security System Using GSM Technology

Abstract

Control of electrical and electronic equipment is very important because of the sensitivity of the devices against the environmental factors, and the most dangerous such as temperature, humidity, fire from the overload or the result of high temperature. Also, from steal or damage by mankind so the purpose of the project is to monitor and control the room remotely for all these reasons. The main idea of this paper is to monitor and protect the control room of radio transmitter devices by using GSM mobile depends on the microcontroller which processes the input data and gives the output signal.The Temperature, smoke sensors were connected to the micro-controller to detect the heating of fire or electricity in the control room. The door-latch opening system using password entered through the keypad. If 3 wrong password entered consequently and the parameters (Temp and smoke) exceed the threshold value, the buzzer turned on.
