PURPOSE: A front door notification device using the light of a sensor lamp is provided to eliminate the need of an extra unit to be operated. CONSTITUTION: A front door notification device is composed of a light-detecting sensor (32), a control part (40), a power supply part (60), and a housing (80). The light-detecting sensor detects the light generated when an internal sensor lamp is turned on and generates a detection signal. The control part is electrically connected with the light-detecting sensor and outputs a notification message stored in a memory through a speaker or outputs a notification phrase through a display device based on the detection signal. The power supply part supplies power to the control part. The housing accommodates the light-detecting sensor, control part, and power supply part and is installed at the wall of a front door, at the outer door surface of a shoe cabinet, at the ceiling, or at the inner surface of the front door, which are close to the internal sensor lamp. |
