Alarm Connection
The sensor has its own hardware alarm function, and the alarm distance can be
set by the host computer. When the sensor measurement distance is less than
the alarm threshold, the alarm line will trigger the alarm level.
Alarm line wiring description: When the measurement distance is less than the
set threshold, the alarm line will generate a low-level signal. The non-alarm
state is a floating state. The circuit recommends using a 100K resistor for
pull-up. When an alarm occurs, the alarm line is pulled down to a low level.
