Design of Automatic Doors for Ultraviolet Sterile Box

There are several ways to sterilize them by using cleaning fluids or by using Ultra Violet (UV) light. However, the use of UV can have adverse effects if exposed to the human body. The current technology is UV sterile boxes for the benefit of UV boxes to be safe from contact with the human body. The box creates a closed space so that UV rays are not exposed to the human body. However, UV sterilizers on the market are not equipped with an automatic system that requires the user to have direct contact with the sterilizer, direct contact with the sterilizer will cause the outer side of the sterilizer to become a new medium for spreading viruses. Based on these problems, we are conducting research that aims to design an automatic door design for UV sterile boxes which are expected to minimize direct contact between the user and the sterile box so that it can stop the development of the coronavirus. Regulate the motion of the dc motor, which must rotate to move the conveyor. Arduino nano will regulate the motor driver, which functions as a switch to change the direction of motion of the dc motor. The rotating dc motor will be connected to the threaded iron to produce forward or backward movement on the conveyor. Arduino nano to it is required to be able to read the value of the proximity sensor as an indicator for stopping the conveyor. Arduino Nano is also needed to regulate the on or off of the ultraviolet lamp. At the same time, the difference in the duration of sending commands by Arduino Nano and receiving system output is 30ms.
