ABSTRACT
The COVID-19 pandemic (Corona Virus Disease 2019) caused by a corona virus called SARS-Co V-2 (Severe Acute Respiratory Syndrome Corona Virus 2) was first discovered in the city of Wuhan, China in December 2019. The spread this virus is very fast, and one of the spread of this virus can be spread through objects around. For this reason, users of online shopping applications are not necessarily packages that arrive at the destination address free from the corona virus. To sterilize online shopping packages, you can sterilize them by spraying disinfectant. Spraying disinfectants can be done manually or automatically, spraying automatically becomes an efficient and practical way to save energy. The manufacture of this automatic disinfectant spraying device uses an Arduino Uno microcontroller as a tool control system, an FC-51 infrared sensor as an object detector, a mini water pump to distribute disinfectants, a door lock for the security system, and other components. By using these components and software that supports the running of the tool, the disinfectant spraying tool can work automatically. This tool is in the form of a box and has two sides of the door, the first door is for the courier door to enter the package and the second door is for the homeowner to pick up the package.
