The invention discloses a smart
human body induction device applied to a
toilet and an application method thereof. The smart
human body induction device comprises a general switch, a
millimeter wave detection module, a comparison module, a control module, a
circuit protection module, a time
delay module, an exhaust fan, a photosensitive induction module and a lighting lamp. The general switch canswitch on and switch off operation of the smart
human body induction device. The
millimeter wave detection module is used for sensing humans or animals in the
toilet and performing imaging. The comparison module determines whether there is a human according to an imaging frame of an accessing animal detected by the
millimeter wave detection module. The control module is used for controlling poweron and power off of the
circuit protection module. The
circuit protection module is used for protecting the normal operation of a circuit. The time
delay module is used for timing and enabling time-delayed power off of an exhaust fan circuit. The photosensitive induction module is used for sensing the intensity of external light and controlling the switching on and off of the lighting lamp. The exhaust fan is used for exhausting air and circulating air. The lighting lamp is used for lighting. The smart human body induction device is convenient and practical, does not require manual operation,is energy-saving and environmentally-friendly, and reduces unnecessary loss.
