PRODUCT DESCRIPTON
The ERDI LASER® LR1000C4 is a next-generation compact 905nm laser rangefinder module designed for high-precision distance measurement in size- and weight-constrained applications. Utilizing Time-of-Flight (ToF) technology, it delivers stable and accurate measurement from 4 m to 1000 m, with an adaptive refresh rate of 3–10 Hz tailored to dynamic application needs.
Its ultra-compact design, low power consumption, and lightweight construction make it ideal for UAV payloads, handheld electro-optical devices, and embedded industrial systems. The LR1000C4 includes a UART-TTL interface, test software, and a communication protocol document, facilitating fast system integration and secondary development. Engineered for reliability and environmental adaptability, it ensures consistent performance in challenging outdoor and industrial conditions.
Key Advantages
- Accurate Long-Range Measurement: Provides ±1 m accuracy within 500 m, and proportional precision for distances up to 1000 m.
- Compact & Lightweight Design: Small footprint (28.8 × 30.5 × 20.9 mm) and ≤16 g weight, ideal for UAVs and embedded systems.
- Adaptive Measurement Rate: Supports 3–10 Hz ranging frequency, configurable for static or dynamic applications.
- Energy-Efficient Operation: Optimized for battery-powered devices with ultra-low standby (<0.3 W) and sleep power (<1 mW).
- Easy Integration & Secondary Development: UART-TTL interface with full documentation and test software for quick deployment.
- Robust & Reliable: High valid measurement rate (≥98%), low false alarm rate (≤1%), and strong environmental resistance (shock, vibration, IP67 lens cavity).
