7. Module power-on sequence diagram
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 2S, and enters the normal
induction mode after a delay of 0.5S.
The following is the control signal after the module is powered on Timing diagram:
8. Schematic diagram of detection range
The sensing sensitivity of the radar sensor can be configured by adjusting the resistance, and its
positive limit sensing distance is 10 meters, and the actual sensing distance can be adjusted
appropriately as needed.
The following schematic diagram of the radar detection range of the typical scene. If the
