When a user approaches the locker, the human infrared sensor detects the signal, and the chip automatically plays the welcome message "Welcome to use XX shared lockers." When the cabinet door is opened or closed, the door magnetic sensor triggers the chip to broadcast prompts such as "The cabinet door has been opened. Please store or retrieve items." and "The cabinet door has been closed. Please leave with peace of mind." providing users with timely and considerate voice feedback.
