AUTOMATIC BODY DISINFECTION TUNNEL OF COVID‑19 VIRUS WITH TEMPERATURE SCANNER AND UV-C RADIATION

Abstract

Preventing the transmission of the COVID-19 in public places involves the use of disinfection tunnels that sterilize the outer body and clothing. However, most disinfection tunnels use conventional systems operated manually with nozzles constantly spraying disinfectant solution. Automation can be used to control the operation, minimizing not only wasteful disinfectant consumption but also physical contact. This paper proposes a control system design for an automatic body disinfection tunnel with a temperature scanner and UV-C radiation. This study uses an ESP8266 microcontroller and several sensors. The disinfectant solution sprayer is equipped with a 2–3 micron nozzle spray and a UV-C lamp of 30 watts integrated with the control unit. The control system is incorporated into a portable and modular arc-roofed disinfection tunnel. The system has been tested and performed with electrical measurements. The results show that the automatic system works and can be implemented as a disinfection tunnel in public areas to optimize transmission prevention.
