Hw416b Pir Sensor Datasheet Better Link

Here are the key parameters extracted from the HW416B datasheet:

Integrating the HW-416B with an Arduino Uno, Nano, or ESP32 is straightforward since it outputs a clean digital signal. Wiring Diagram Connect HW-416B to Arduino 5V Connect HW-416B GND to Arduino GND Connect HW-416B OUT to Arduino Digital Pin 2 Optimized Arduino Sketch

After the sensor detects motion and the output goes high, if further motion occurs during the delay time, the timer resets. The output stays high until motion ceases. hw416b pir sensor datasheet better

The HW416B outputs 3.3V, which is safe for 5V Arduinos, but 5V logic can damage 3.3V-only boards. To be better safe than sorry:

Repeatable Trigger: The delay timer resets with every new movement detected, keeping the output high as long as there is continuous motion. Here are the key parameters extracted from the

The is a high-quality, adjustable module widely regarded as a reliable alternative or "clone" of the standard Go to product viewer dialog for this item.

Most “datasheet problems” are actually tuning problems. If your HW-416B triggers randomly: The HW416B outputs 3

As useful and popular as the HW416B is, it's not a perfect sensor. If you're facing persistent issues or need more advanced features, consider these alternatives:
