Abstract
Shopping malls and retail clothing outlets have high customer footfall. Particularly in clothing trial rooms, where garments are repeatedly tried by different individuals. This repeated usage poses a substantial risk of transmission of contagious diseases and fungal infections through contaminated garments and enclosed environments. This proposed model represents an Arduino-based smart trial room system integrating RFID-based clothes tracking and time-based billing, automated UV-C (254 nm/FTL) sanitization, and real-time environmental risk assessment. Environmental parameters such as relative humidity, temperature, occupancy count, CO2 concentration, and surface moisture are monitored to determine a fungal and contagious disease risk index. Based on the estimated risk, dehumidification, automated control of ventilation, and UV sanitization is performed. The proposed model demonstrates a reduction in high-risk conditions, improved hygiene obedience and significantly reduces the risk of contagious diseases while preserving operational efficiency and ensuring customer safety.
