Abstract

Malaysia is a country located on the equator line. Therefore, the weather conditions in Malaysia are uncertain. Because of this, the clothes that consumers wash become difficult to dry when it rains. Besides that, they also lack the time to hang and lift the clothes because they are busy with outdooraffairs. This project usesthe solar system as a source of electricity to generate this automatic clothesline system and PLC CPM1A is as Microcontroller to include all the programs that will give instructions to run the system so that it can work automatically. This project has two modes which are manual and automatic mode. Manual mode is controlled by a push button switch to turn the clothesline in and out while the automatic mode is controlled by all the inputs signal. This project needs a DC motor as an output to convert electrical energy into mechanical energy to be able to pull in and out of the clothesline. Automatically, the clothesline will pull in if the rain sensor detected water or the temperature sensor detected a temperature below 24.5 degrees celcius and LED will turn on. If the light sensor detected light above 150 lux the motor will push out the clothesline.
