The invention provides an intelligent toilet door based on motion recognition. The intelligent toilet door comprises a door body, a controller, a door opening inductor, a locking-out inductor, a microwave sensor and an electromagnetic lock, wherein a first infrared induction band and a first temperature comparator are arranged in the door opening inductor; a second infrared induction band and a second temperature comparator are arranged in the locking-out inductor; the microwave sensor can detect the movement of a human body in a toilet; the electromagnetic lock comprises an excitation coil; the first temperature comparator, the second temperature comparator and the microwave sensor are respectively connected with the controller; the controller is connected with the excitation coil, and the controller can control forward current or reverse current to pass through the excitation coil so as to realize locking or unlocking respectively; and the controller is also connected with the firstinfrared induction band, and when the door body is locked out, a door opening sensor outside the door body is controlled to be temporarily powered off. The intelligent toilet door is strong in anti-interference capability, can be automatically opened or closed by accurately identifying motion signals.
