Sourcing LiDAR Sensor Modules from China
1 resources tagged with "Lidar"
China is the volume source for LiDAR modules, with Hesai, Robosense, and DJI's Livox covering spinning, solid-state, and MEMS designs for robotics, AGVs, and ADAS. The first technical fork is wavelength: 905nm units are cheaper and dominate consumer/robotics work, while 1550nm fiber-laser units reach further but cost several times more. Budget for export-control friction too, since automotive-grade LiDAR has drawn end-use scrutiny.
When you actually buy LiDAR, point density, range, and ROS/ROS2 driver support matter more than the marketing range figure measured against a 90% reflectivity target. A common pitfall is assuming a quoted range holds against a 10% reflectivity object like a black car or dark pavement, where real range can drop by half.

FAQ
What is the difference between 905nm and 1550nm LiDAR?
905nm uses silicon detectors, is cheaper, and is eye-safety limited at longer range; 1550nm uses fiber lasers, sees farther, and costs several times more. Most robotics and AGV projects use 905nm; long-range automotive often goes 1550nm.
Are there export-control issues buying LiDAR from China?
Automotive and high-end mapping LiDAR can face end-use and re-export scrutiny on both sides, so confirm the model's classification and any required documentation before committing volume orders.
Do Chinese LiDAR modules support ROS?
Mainstream brands like Hesai, Robosense, and Livox ship ROS/ROS2 drivers and point-cloud SDKs. Verify the exact driver matches your firmware version before integration, as older units sometimes lag the latest ROS release.
