for the small chip that is soldered in, and see that it has an out.
That pin is your focus, you have to try to identify the way it works.
The CDS looks like an enabler/disabler from the description on the
second pic.
Translation from the Chinese description:
Big Pin Power YEE Description:
1: 3V3 3, 3W output voltage, the drive current 100 tha
2: GND Module ground.
3. OUT output control signal when moving objects within the detection region, lost two high bite: When C- TI can be set to trigger repeat, if there is only the trigger signal in the repeat time (there was more secluded area Aj detection labor movement have . move), continuous output high; if there is no movement within the detection area neighborhood, lose low.
4: VIN mold slope power input, 4-78
5: CDS trigger control signal is less than 0, TY, OUT output has been low! Greater than aTY, noise measured normal operation CDS pin external photosensitive resistance can be at night and closing module subject O function identification

that basically covers the basic functionality.
for configuration, the pads on the back are as follows:

RCWL-0516 microwave radar sensor module Human body induction switch module Intelligent sensor
for configuration, the pads on the back are as follows:
- C-TM - adjusts repeated triggering time by adding a capacitor here. pin3 of the IC emits a frequency, and the tigger time in seconds is given by (1/f)*32678
- R-GN - default detection is 7m, adding a 1M resistor reduces it to 5m.
- R-CDS - can add a photoresistor here, which gets attached between VCC and then through a 1M fixed resistor and then to the CDS (enable). this allows the unit to stop sensing at night. (not exactly sure how you'd adjust this... )
