DTOF LD19 Laser LiDAR Sensor Kit (12m)

The LD19 is a compact 360° DTOF (Direct Time-of-Flight) LiDAR sensor with a ranging distance of up to 12 metres. It provides high-frequency environmental scanning for autonomous mapping, obstacle detection, and navigation. The sensor resists ambient light up to 30 kLux, enabling reliable operation both indoors and outdoors.

The included SDK supports ROS1 and ROS2, and the sensor communicates via UART at 3.3 V. A brushless motor drives the scanning mechanism for long-lasting, reliable operation.
