Sistem Pengendali Mesin Air Otomatis Menggunakan Mikrokontroler Arduino

At this time the filling of water in the tank / tank that is using a water machine, where the water machine functions to suck and put water into the tank. The water tank is usually used as a reservoir for clean water for daily household needs, especially those that suck water from the well. The water filling work system still needs full supervision. The water machine must be started if the water reservoir is empty and the engine must be turned off when it is full. This is quite troublesome, if you forget to turn off the engine, then the water in the reservoir will be full until it overflows and this will get a loss that is wasteful of water and waste of electricity usage. Current technological developments encourage people to continue to think creatively, not only to explore new discoveries, but also to maximize the performance of technology, especially microcontrollers to be used as an aide to the work done every day. Microcontroller is one of the developments of the microprocessor, which is a chip that can process data digitally with specific language commands used. Microcontroller is also often used as an electronic circuit controller, which can store a program in it. With the development of electronics and microcontroller technology, it is a solution to reduce the problem of water waste. For that we need the role of technology and electronics that can create an innovation to overcome these problems. Therefore we need a system that is able to control and control water usage automatically. When the water tank is empty, it will automatically start, and if it is full, it will automatically turn off. With this system, it is expected to help humans use water and electricity more effectively and efficiently
