Radiological equipment disinfection is one of the disinfection processes that must be routinely carried out in order to prevent transmission during a pandemic. Wall bucky stand is a chest x-ray examination tool that has a part where the chin is placed so that it can transmit the Covid 19 virus. This research aims to design and develop a disinfection tool that is designed to work automatically to conduct disinfection in the wall bucky stand using an Arduino Uno microcontroller. The design components include pump steam, sprayer, adapter, microcontroller, buzzer, and PIR sensor. Component analysis is made based on the design of the x-ray room and the size of the wall bucky stand. The microcontroller is utilized to set the disinfectant spraying time automatically upon the patients' movement detected through the PIR sensor. This study is an initial study to produce a prototype of an automatic disinfection tool with a microcontroller. The equipment specifications use an Arduino Uno R3 SMD CH340 ATMEGA328P microcontroller, HC-SR501 PIR Motion Sensor Module, and hollow cone nozzle, with a spraying time of 2 seconds, which is done after waiting 60 seconds without detection of patient movement. With the above specifications, disinfectant spread, the sensor work's precision and the spray time are effective.
