Usage Guidelines
- Electrical Connection
- Ensure 3.3V power supply and correct UART-TTL wiring (refer to pin definitions in Section 2.2.2).
- Optical Window Maintenance
- Keep the optical window clean and free of fingerprints, dust, or scratches to maintain accuracy.
- Environmental Considerations
- Avoid measuring highly reflective targets at close range to protect detector components.
- Do not use in polluted environments or beyond specified storage temperatures.
- Safety Precautions
- Never disassemble or adjust internal components.
- Avoid direct eye exposure to the laser beam.
