If you want, I can convert this into a printable one-page PDF datasheet layout, produce schematic wiring examples, or provide sample Arduino and Raspberry Pi code snippets for the HW-416-B.
If you are integrating this sensor, treat the "Distance" potentiometer as a "Motion Size" filter, not a range extender. If you need true range adjustment, you must physically swap the Fresnel lens dome, not turn the screw.

The is a highly efficient, low-cost electronic module designed to detect human or animal movement. It is widely used in smart home automation, security systems, and energy-saving lighting projects. By capturing changes in infrared radiation emitted by living bodies, this compact sensor provides an easy-to-use digital output for microcontrollers.
The module has two small, blue potentiometers (often marked with small cross‑slots) that let you tune its behaviour:
What are you trying to trigger (a relay, a buzzer, an LED strip)?
