The HC-SR501 module is an automatic control module based on infrared technology, adopts a probe design with high sensitivity, strong reliability and a low-voltage working mode, can realize full-automatic induction, and can output high level when a person enters an induction range of the probe design and automatically delay to close the high level and output low level when the person leaves the induction range. The triggering mode of the HC-SR501 module is divided into a repeatable triggering mode and a non-repeatable triggering mode, and in the non-repeatable triggering mode, after the high level is output in a sensing mode, the time delay period is finished, and the output is automatically changed from the high level to the low level. When the triggering mode can be repeated, after the high level is output by sensing, in a delay time period, if a human body moves in the sensing range, the output of the human body keeps the high level all the time, and the high level is changed into the low level in a delayed manner until the human body leaves.
