Summary: The global health-threatening COVID-19 pandemic resulted in distance learning and a new normal setting for students, professors, and other employees. Germicidal lamps have proven to be an effective tool for disinfecting bacteria and viruses. The current method for disinfecting viruses and bacteria is liquid-based, which has limitations, particularly if the item to be disinfected is constructed from paper. The goal of this research is to develop a dry-based disinfection system that uses Ultraviolet Light integrated in an automated conveyor belt with sensors to kill microorganisms such as bacteria and viruses. It is made up of three components: the conveyor belt, the UV box, and the control board. We used a 12V DC motor and a photoelectric sensor on the conveyor belt, LCD display, an Arduino Uno, two buttons, an external potentiometer, a power switch, and a fuse on the control board. The UV light shows consistent dosage results after 5 trials of 3 seconds, 5 seconds, 7 seconds, 9 seconds, and 10 seconds. For 3 seconds, the value is 25mJ/cm2, for 5 seconds, the value is 25mJ/cm2, for 7 seconds, the value is less than 50mJ/cm2 but greater than 25mJ/cm2, for 9 seconds, the value is 50 mJ/cm2, and for 10 seconds, the value is 50 mJ/cm2. We sampled 20 users to determine how well the system is accepted by its users and received an overall mean score of 4.54, corresponding to a 90.8% acceptability rate. The Virus Disinfection: UV Light Sterilizer System was engineered, designed, and validated to disinfect objects effectively, emitting a precisely safe 72.65 mJ/cm2 UVC dosage and obtaining an "Excellent" rating in usability, functionality, performance, and compatibility by evaluating it at the Technological University of the Philippines.

The global health-threatening COVID-19 pandemic resulted in distance learning and a new
normal setting for students, professors, and other employees. Germicidal lamps have
proven to be an effective tool for disinfecting bacteria and viruses. The current method for
disinfecting viruses and bacteria is liquid-based, which has limitations, particularly if the
item to be disinfected is constructed from paper. The goal of this research is to develop a
dry-based disinfection system that uses Ultraviolet Light integrated in an automated
conveyor belt with sensors to kill microorganisms such as bacteria and viruses. It is made
up of three components: the conveyor belt, the UV box, and the control board. We used a
12V DC motor and a photoelectric sensor on the conveyor belt, LCD display, an Arduino
Uno, two buttons, an external potentiometer, a power switch, and a fuse on the control
board. The UV light shows consistent dosage results after 5 trials of 3 seconds, 5 seconds,
7 seconds, 9 seconds, and 10 seconds. For 3 seconds, the value is 25mJ/cm2, for 5 seconds,
the value is 25mJ/cm2, for 7 seconds, the value is less than 50mJ/cm2 but greater than
25mJ/cm2, for 9 seconds, the value is 50 mJ/cm2, and for 10 seconds, the value is 50
mJ/cm2. We sampled 20 users to determine how well the system is accepted by its users
and received an overall mean score of 4.54, corresponding to a 90.8% acceptability rate.
The Virus Disinfection: UV Light Sterilizer System was engineered, designed, and
validated to disinfect objects effectively, emitting a precisely safe 72.65 mJ/cm2 UVC
dosage and obtaining an "Excellent" rating in usability, functionality, performance, and
compatibility by evaluating it at the Technological University of the Philippines.
