For the description of the high-level and low-level trigger modes, if you dont understand, please take a look:

High-level trigger refers to the trigger mode in which there is a voltage between the signal input terminal and the ground, which can be understood as a short-circuit trigger mode between the signal input terminal and the positive VCC;

Low-level trigger refers to the trigger mode where the voltage between the signal input terminal and the ground is OV, which can be understood as a way of triggering by a short circuit between the signal input terminal and GND.
