Connecting the HW-416-B to an Arduino is straightforward because its 3.3V output is compatible with most digital pins. HW-416-B Pin Arduino Pin Digital Pin 2 Example Code Snippet HW-416B: PIR MOTION SENSOR FOR ARDUINO
Copy this article into a Word document, save as PDF, and you’ll have an unofficial but complete HW-416-B datasheet reference for your workshop. hw-416-b pir sensor datasheet
The HW-416B caught the shift in infrared radiation. The pin went HIGH, the Arduino chirped, and Leo grinned. The snack drawer was officially guarded by the watchful, faceted eye of the PIR.
