high, the sensing pull-up time is 2 seconds; when P3 is pulled low, the sensing pull-up time is 15
seconds. If there is a new trigger during the inductive output pull-up period, the inductive time will
be extended.
6. Photosensitive detection
The module supports photosensitive detection. The sample module does not enable the
photosensitive detection function by default.
The position shown in Figure 5 is a photosensitive diode. The photosensitive threshold can be
adjusted by changing the photosensitive judgment threshold or tuning the photosensitive resistance.
In the version with photosensitive function, the radar sensor will be activated only when the
ambient light is lower than the set illuminance.
If the light is too bright, the module will not activate the sensor function. (After the photodiode is
mounted in a bright environment, the current consumption of the module will increase by about
5uA)
