@thesis{thesis, author={Alwi Ahmad}, title ={Rancang Bangun High Medium dan Low Level Tangki Bahan Bakar (Solar)}, year={2022}, url={http://eprints.polbeng.ac.id/7425/}, abstract={The desire to always create a work has undergone gradual changes that are competitive in nature in order to create convenience for the humans themselves, which are supported by increasingly sophisticated devices. This monitoring model is to create an early warning system if the diesel in the fuel tank has started to run out. The system in the prototype consists of a diesel tank, a control circuit, an XKC Y25 sensor based on an Arduino Uno microcontroller. XKC Y25 sensors are placed in a row of high, medium, and low on the side of the tank. Where the XKC Y25 sensor will detect the state of the tank then the control circuit sends the characters that are displayed on the LCD as a viewer of the state of diesel in the fuel tank. The LCD display will display the state of the tank, whether low, medium or high, when in a low state, a warning sound from the buzzer appears. From the research conducted, it was obtained based on a prototype test carried out on the state of the fuel tank using the XKC Y25 sensor, which can work well to measure high medium and low level diesel tanks use plastic materials while for metal materials the xkc y 25 sensor cannot detect the liquid state in it.} }
