Based on behavior observed from multiple HW-416-B units: hw-416-b pir sensor datasheet

: The 3.3V logic output is compatible with both 3.3V and 5V microcontrollers without needing a level shifter. 6. Environmental and Mechanical Considerations | Parameter | Min | Typical | Max

The is a reliable, low-power motion detection module ideal for microcontroller projects requiring a fast response and compact footprint. While an official unified datasheet remains elusive, the specifications and behavior described in this article are based on reverse-engineered measurements and manufacturer-compliant components. While an official unified datasheet remains elusive, the

The module typically features three main pins for connection and two potentiometers for fine-tuning performance. Connect to 5V–20V power source.

The HW-416-B does not "see" light like a camera. Instead, it detects .
