Abstract

This research designed a home security system system with monitoring using cellular phonenetwork. This tool is designed for easy homeowner in the house and locking the door to notice thecondition of the house when the door was left empty, the medium used is a mobile phone by using SMS facility. This device consists of a sensor is a magnetic switch that serves as an input to tell the condition of the door to the microcontroller, ATmega8535 microcontroller is used. Then the keypad which serves as input a password and a GSM modem that serves as a SMS sender and receiver. This security system has been built on the principle if there are people who do not have a password / access code as an entry into the house, then the system will activate the warning / alarm by sounding a warning buzzer and send SMS text notification of the "Intruders" to the phone number which has been programmed into the microcontroller.

Abstract

In this research, the warning systems and monitoring of SO2 gas conditions designed using sms gateway technology with assistance MQ136 sensor gas to detect the presence of SO2 gas and ATmega16 microcontroller as the processor. The SO2 gas concentration value will indicate a condition with a normal, alert, or hazard warning, it can be determined and determined from the laboratory test results. SMS will be sent to five number of destination if the concentration exceeds the threshold value set. System monitoring is done by sending an sms to device which contained by command to transmit gas concentration values which detected via sms to the number of the sender. This device is also equipped with a gas alarm if condition is danger and will stop ringing if it is below the danger threshold.
