Abstract Lighting loads in a room normally operated manually by humans. With the current technological advances, human intervention in the operation of trying rcduced. Automated systems will be able to facilitate operations. Effective anci efficient to avoid the lighs are on in vain without any activity. Another objecti"e was to avoid the waste of electrical energy. The topic for the final task of making automatic lights to operate the lighting load of a room. The automated system uses presence sensor input type passive infrared or PIR. Including PIR sensor pyroelectric type of heat that has no heat change instantaneous response. Source of heat radiated by the infra red. The human body produces heat energy radiated by infrared. Heat radiation the human body will be received sensor input circuir for the response. Consists of a comprehensive range of passive infrared sensor, relay. main circuit, power supply, as r..,ell as light v,,eight. In essence this PIR will be the driver transistor. Transistors function as an electronic switch that will disconnect and connect beban.Kebutuhan for security is one thing that is very important in human life. By using i6F8?7A PIC PIR sensor, to detect human movement. When the PIR sensor detects human motion sensor will produce a logic and a value of I (one), then the output of the PIR sensor will be heading to the inpur delay circuit, wherein the delay circuit to function as a regulator of the activation of the relay lamp drivers. When no movement is detected by the scnsor system will work with the indication lights on. after 0.5 seconds no movement and the light goes off. For a spacious room needs to increase the number of sensors that can detect human movement in a room, and to be able to use more reliable heat type thermopile sensor.
