For descriptions of high levels and low level triggers, friends who do not understand, please take a look:

High -level trigger refers to a voltage trigger method between the signal input terminal and the ground. It can be understood as a way to trigger the signal input terminal and VCC positive pole short circuit;

Low -level trigger refers to the trigger method of the voltage between the signal input terminal and the ground. It can be understood as a way of the signal input terminal and the GND negative short circuit trigger.
