A light-sensing cabinet with password protection, comprising a cabinet body, a cabinet door movably provided at a front portion of the cabinet body, a driving device for opening and closing the cabinet door, a central control circuit for controlling the driving device, and light-sensitive components placed at multiple areas on an external portion of the cabinet door. When a user stands in front of the cabinet and blocks multiple light-sensing components and when the light-sensing components detect that a light level is lower than a preset value, the components control, by means of the central control circuit, the driving device to automatically open the cabinet door. The user therefore does not need to manually open the door, achieving a high degree of automation. A light intensity threshold can be adjusted by using a connected intelligent device. The light-sensing components are provided at multiple areas to avoid unintended opening of the cabinet door caused by an accidental blocking of the light-sensing component at a small area. The invention has a high degree of intelligence and can be easily incorporated into a smart home.
