7. Odpravljanje težav
| Težava | Možen vzrok | rešitev |
|---|---|---|
| Brez zaznavanja ali nedosledno zaznavanje | Incorrect power supply; Obstruction in detection path; Incorrect sensitivity settings; Outdated firmware. | Verify 5V DC power supply; Ensure clear line of sight for radar or use appropriate non-metallic enclosure; Adjust sensitivity and distance parameters; Check for and apply firmware updates. |
| Module not responding via serial interface | Incorrect wiring; Incorrect serial port settings (baud rate, etc.); Module damage. | Check pin connections (TX/RX, GND, VCC); Confirm serial port settings match module specifications; Test with a known working module if possible. |
| Lažna odkrivanja | High sensitivity; Environmental interference (e.g., strong vibrations, large moving objects outside intended zone). | Reduce sensitivity; Refine detection zones; Ensure proper mounting to minimize vibrations. |
