What Is a Hands-Free Door Opener?
A hands-free door opener is a device that allows you to open doors without touching the doorknob or lever.
It operates in two basic modes: proximity detection mode and voice recognition mode, each detecting the presence of a person or voice to open and close the door. There are two types of connections: power supply type and battery-powered type, utilizing either a power cord or built-in batteries.
The operational principle involves sensors detecting the presence of a person or voice, based on which the control circuit regulates the door-opening motor for opening and closing. It finds applications in various settings such as hospitals, care facilities, factories, warehouses, commercial establishments, and households. Its features include touchless operation, excellent hygiene, and user-friendliness for the elderly and people with disabilities.
