TOFSense laser ranging sensor is based on the principle of TOF flight time, the blind zone in the series is less than 2cm, the distance is up to 25m, covering single point, multi-point, 2~63 ° FOV angle, UART, CAN, IIC, IO multiple communication interfaces. Cascade ranging is supported in the series to reduce the resource occupation of the communication interface, and the active output and passive query meet different development architectures. The system fully opens the communication protocol to adapt to various deep integration requirements. Detailed development materials such as ROS, APM, C language drivers and real-time technical support help developers easily get started, which are widely used in scenarios such as robot obstacle avoidance, UAV height determination, detection and measurement, hydraulic stacking inspection, and personnel detection.
