Main Functions
a) Distance Measurement & Real-Time Reporting: Accurately measures and stably reports target distances. Ensures no zero jumps or false readings during continuous measurement of stable targets.
b) Single/Continuous Measurement Modes: Supports both single-shot and adjustable-frequency (1–5Hz) continuous ranging.
c) Laser Emission Count Reporting: Tracks and reports total laser pulses for maintenance monitoring.
d) Self-Diagnostic Function:
- Automatic power-on self-test (POST).
- Command-triggered self-test to verify critical component status (laser health, APD voltage, temperature).
e) Fail-Safe Protection:
- Wide-voltage input design (10–14V DC).
- Reverse polarity protection to prevent damage from incorrect wiring.
Applications
- Drones & UAVs (navigation, mapping)
- Robotics & automation (obstacle detection)
- Industrial surveying & construction
- Outdoor sports (hunting, golf, mountaineering)
- Security systems & traffic monitoring
