This tool explains how to work a series of cell phone signal detector when detecting the use of mobile phones (GSM) in the room. If the signals were detected mobile phone (GSM) in the room then this tool will give you a sign in the form of LED light is flashing, and the sound generated by the buzzer so that it can be heard when there is use of mobile phones in the room. Where Microcontroller ATmega8535 used as a controller circuit, when the process has been detected for the use of mobile phone signal in the room that will be sent to the MAX232 IC. MAX232 IC serves as a serial communication between the microcontroller ATmega8535 wavecom modem used for sending SMS (Short Message Service) on mobile phone monitoring officer. Mobile attendant monitoring function to receive SMS (Short Message Service) sent from the modem wavecom, so the officer can know that there is the use of mobile phone signal indoors. This tool can be used during the exam, places of worship, offices, and correctional institutions. Keywords: Cell Phone Detector, ATmega8535 microcontroller, IC MAX232, Mobile
