Hw-416-b Pir Sensor Datasheet |work| Jun 2026

If you are incorporating the HW-416-B into a final product:

While the HW-416-B shares similarities with the classic HC-SR501, it has distinct PCB layout, lens mounting, and sometimes different time delay ranges. This article serves as the missing comprehensive datasheet, pulling data from manufacturer specifications, reverse engineering, and field tests. hw-416-b pir sensor datasheet

The is a reliable, low-power motion detection module suitable for a vast range of applications. Its datasheet – though not always easy to find as a single official document – reveals a robust design centered around the BISS0001 controller, with adjustable sensitivity, timing, and dual trigger modes. If you are incorporating the HW-416-B into a

The output goes high once motion is detected and stays high for the set delay time, then goes low regardless of continued motion. Its datasheet – though not always easy to

Note: Some variations of the board may swap VCC and OUT. Always verify the silkscreen print on the PCB itself before wiring to avoid damaging the component.
