Note: High level trigger refers to the trigger mode with 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 VCC positive pole.

Low-level trigger means that the voltage between the signal input end and the ground is triggered by OV,
which can be understood as a short circuit trigger between the signal input end and GND negative pole
