start the sensing function. When testing the radar
performance alone, the photodiode can be covered with
black tape to avoid the photosensitive effect affecting
the radar sensing function.
Power on Sequence
The module has a power-on self-check function, that is, after the module is powered on, the OUT
pin first outputs a high level, and then outputs a low level after a delay of 3S, and enters the normal
induction mode after a low level delay of 0.5S,The following is the sequence diagram of the control
signal after the module is powered on:
