At its core, the touchless tunnel employs a combination of sensors, automated systems, and smart technology. As an individual approaches the entrance, motion sensors detect their presence, triggering a sequence of events that initiate automated functions. This could include the opening of doors, activation of sanitizing sprays, and air purification systems. As people pass through the tunnel, they receive a thorough disinfection without needing to physically touch any surfaces. This not only enhances personal safety but also alleviates anxiety in environments where health concerns are paramount.
