Automatic switch for light and fan using PIR sensors that application in polytechnic mosque is a device to easy someone to turn on and turn off lamp and fan with using sensors as detection human. So people dont need to turn on and turn off lamp and fan manually when they left or enter the mosque because this sensor will active when sensor detect if there is a human moving and nonactive when there is no human moving . PIR sensor have fuction to detect human moving and then output of PIR sensors will connect to microcontroller. Data from microcontroller will process to activated relay. After relay has active, relay as a automatic switch will turn on lamp and fan in mosque. Trial of all of this sistem is succes and be evidenced with value of trial of this devise and data from value of devise the amount of power consumption before and after this devise installed in mosque. We can see the amount of power consumption for 24 hour after this devise is installed 90.56 Wh and can save power about 2.89 Wh if we compared before this device is installed.
