PRODUCT DESCRIPTON

The ERDI LASER® LR1000C3 is a new-generation compact 905nm laser rangefinder module designed for high-precision distance measurement in size- and weight-sensitive applications. Based on advanced Time-of-Flight (ToF) technology, it provides stable and accurate ranging from 4 m to 1000 m, with an adaptive refresh rate of 3–10 Hz to meet dynamic measurement requirements. 

With its ultra-compact structure and low power design, the LR1000C3 is ideal for integration into UAV payloads, handheld electro-optical devices, and embedded industrial systems. The module supports a UART-TTL interface and is delivered with test software and communication protocols, enabling fast integration and efficient secondary development. Designed for reliability and flexibility, it performs consistently across various environments, making it suitable for both portable devices and professional measurement systems.

Key Advantages

  • High-Precision Ranging Performance: Delivers ±1 m accuracy within 500 m and enhanced precision for extended distances up to 1000 m.
  • Ultra-Compact & Lightweight: Small form factor (30 × 19 × 29 mm) and ≤16 g weight, ideal for compact systems and UAV integration.
  • Adaptive Measurement Rate: Supports 3–10 Hz adjustable ranging frequency for both static and dynamic applications.
  • Low Power Consumption Design: Optimized for embedded and battery-powered devices with ultra-low standby and sleep power.
  • Easy Integration & Development: UART-TTL interface with full protocol documentation for seamless system integration.
  • Reliable & Robust Performance: High measurement reliability (≥98%) with low false alarm rate (≤1%) and strong environmental adaptability.
