PRODUCT DESCRIPTON
The ERDI LASER® LR1000D25 is a compact 905nm laser rangefinder module designed for precise distance measurement up to 1000 m. The module integrates a stable optical system, optimized signal processing, and a UART-TTL interface, enabling reliable performance in electro-optical and embedded applications requiring accurate and efficient distance sensing.
Key Advantages
- High Measurement Accuracy Across Full Range: Optimized ranging algorithm achieves ±1 m accuracy at short-to-medium distances and improved proportional accuracy at longer distances.
- Compact Mechanical Structure: Small cylindrical design (Ø25 mm × 46.1 mm) supports easy integration into portable electro-optical equipment and UAV payloads.
- Stable Measurement Performance: High valid measurement rate (≥98%) and low false alarm rate (≤1%) ensure reliable distance output in practical environments.
- Configurable Ranging Frequency: Adjustable measurement frequency from 3–10 Hz allows flexible adaptation to dynamic or static measurement tasks.
- Low Power Consumption: Average power consumption below 0.8 W supports battery-powered and embedded system applications.
- Integration-Friendly Interface: UART-TTL communication protocol simplifies system integration and secondary development.
