01
Day & Night Long-Range Precision Ranging
Equipped with a 905±5 nm Class 1 eye-safe laser, the JV-LRF902CD delivers stable long-range measurement in both daytime and nighttime conditions. It supports building-target ranging ≥1200 m by day and ≥2000 m at night, with ≥800 m ranging for 0.5×1.7 m small targets, providing reliable distance data for outdoor observation and monitoring applications.
02
Ultra-Compact Integration & High Measurement Reliability
Designed for embedded optical systems, the module combines compact construction, low power consumption and a standard 3.3 V TTL UART communication interface. With a valid measurement rate of ≥99%, distance resolution of ≤0.1 m, startup response within ≤100 ms and adaptive 1–10 Hz measurement frequency, it is suitable for integration into night vision devices, surveillance PTZs, UAV payloads and inspection platforms.
