Penggunaan Raspberry Pi sebagai Web Server pada Rumah untuk Sistem Pengandali Lampu Jarak Jauh dan Pemantauan Suhu

In this thesis designed a system that can be used to control lamps and electric water pump that applied at home remotely with a web page interface that can be accessed by using the internet or local area network via a PC or smartphone. The system was made in this thesis also has timetable facility and can be used to monitor the room temperature. There is one master module and two slave modules that have been designed previously. The workings of the system that has been made is Raspberry Pi module will transmit the data obtained from the user via a web page to modem PLC module using serial communication to be forwarded to the slave modules using the power line cable to produce a command for controlling device connected to the slave modules. On the results of testing , the entire system perform the control using internet network via a PC success rate is 90%. In the test without using the internet via a smartphone success rate is 92%. As for test results through timetable success rate is 95%. Failure in the control device when the data transmission controlled from the master modul to slave modules at the same time with the data transmission of information from the slave modules to master module, it is because the master module and slave modules communicate in half- duplex mode. However, the failure can be unknown directly by the user with view the pictures indicators exist on the web page. When the indicator image on a web page does not change, then there is a failure in the control device so that the user can repeat the command for controlling the device
