KRISTIANTO, DANI EKO (2008) RANCANG BANGUN SISTEM KEAMANAN RUMAH MENGGUNAKAN SENSOR PASSIVE INFRA RED KC7783R DAN LM35 BERBASIS MIKROKONTROLER AT89S51. Undergraduate thesis, Department of Physics, Diponegoro University.
A design home security system by using Passive Infra Red censor and LM35 temperature censor based on microcontroller AT 89S51. This system can detect fire and theft and also switch-on and switch-off the light automatically. If the house in dangerous condition then system will switch-on buzzer or water pump when fire happened. This system consist of hardware and software. The hardware consist of a motion sensor, temperature sensor, comparator non inverting, driver relay,eksternal timer, a microcontroller, and seven segment used to display clock. The software consist of the program use assembly Ianguages where implementation on microcontroller. This system can be activated any time according to occupant by press power button on panel. To switch-off buzzer and water pump can be performed by press button reset on the side of power button. So if house in the dangerous condition, then alarm will be ring or water pump will be switched on when fire happened. To setting light on or off can be set by program microcontroller. This system was realized and can detect theft if one of the motion sensor which attached in each door triggered or identify fire if temperature censor detect house’s temperature reach 40ºC also can switch-on or switch-off house’s light automatically according setting time.
