Control method for intelligent toilet cover based on single infrared sensor

A control method for an intelligent toilet cover based on a single infrared sensor, comprising the steps of:

• detecting a presence of a human body using an infrared sensor (130), and transmitting detected signal to a first control module (101) to control a second opening/closing mechanism to lift the toilet cover (12), wherein the infrared sensor (130) has a first sensing distance range;
• controlling a sensing distance range of the infrared sensor (130) to shorten the sensing distance range from the first sensing distance range to a second sensing distance range;
• and
• sensing a hand motion and generating a hand motion signal by the infrared sensor (130), and transmitting the hand motion signal to the first control module (101) to control a first opening/closing mechanism to lift a seat (11) or to perform flushing, then controlling the second opening/closing mechanism and the first opening/closing mechanism to lower the seat (11) and the toilet cover (12).
