01
Day & Night Long-Range Precision Ranging
Equipped with a 905±5 nm Class 1 eye-safe laser, the JV-LRF902BD provides stable long-distance measurement in both daytime and nighttime conditions. It supports building-target ranging up to ≥1200 m by day and ≥2000 m at night, while 0.5×1.7 m targets can be measured up to ≥800 m, delivering reliable ranging data for outdoor observation and monitoring applications.
02
Ultra-Compact Integration & High Measurement Reliability
With dimensions of ≤22.5×15.5×9.5 mm and a weight of ≤5 g, the module is designed for compact embedded systems. It provides a ≥98% valid measurement rate, ≤0.1 m distance resolution, ≤100 ms startup response and single-shot or 1–10 Hz ranging through a UART TTL 3.3 V interface, making it suitable for integration into surveillance devices, inspection systems and other compact optical platforms.
