This study aims to design and create a safety device and automation system in the use of air conditioner (ac) use in-vehicle units, especially in four-wheeled vehicles based on Arduino UNO microcontroller Atmega 328. The safety device system created in this study used Arduino UNO as its microcontroller, a tool was equipped with a PIR sensor that was positioned in the cabin and a limit switch placed at the door of the vehicle. If there are humans inside the vehicle unit, the PI sensor will detect movement, and if the unit door is in the closed position, the limit switch will be depressed. The principle used the AND logic gate principle where both inputs both the PIR sensor and the limit switch must work together to turn on the AC, but if only one input works, then the AC will not turn on. The results of this study indicated the tool could work under the design that has been done, and the programming of the safety device can work well according to the desired working principles through the programming commands on the Arduino UNO microcontroller.
