PERINGATAN DINI PADA SISTEM KEAMANAN RUMAH DENGAN FASILITAS SMS (SHORT MESSAGE SERVICE) TELEPON SELULER

Have been designed and used, home security system by using mobile phone with make use short message service (SMS) facility. This system can be used to supervise home condition when it was leaved by the host or when no body at home, so home condition will be always supervised and secure without any security to guard it. This system uses 2 pieces Sensor Passive Infrared (PIR) to detect if there is someone enter a house and for giving the dangerous warning it uses sms facility at mobile phone which will be sent to certain number with buzzer sound. The destination number and sms content is formatted on Protocol Data Unit (PDU) which has been saved on microcontroller program. From the research has been done the result is, if there ishave been rain so the sms content will be sent is “TURUN HUJAN”, if there is 1 sensor which is set outside of the house detected so the sms content will be sent is “ADA YANG DATANG!!” and if the second sensor which is set inside the house detected so the sms content will be sent is “ADA YANG MASUK!!” and the same time buzzer will be on to give warning for people around the house
