SLAMTEC RPLIDAR S3 LiDAR Sensor 40m Range 32kHz SL-TOF TTL UART IP65 for Robotics & SLAM

Overview

The SLAMTEC RPLIDAR S3 LiDAR is a compact scanning LiDAR sensor designed for indoor and outdoor ranging and environment perception, featuring reliable resistance to daylight (>=80Klux / 80,000Lux anti-interference ability of ambient light). It supports a stable 40-meter measurement radius for white objects under 70% reflection and provides high-speed sampling for mapping and obstacle detection tasks.

Details

RPLIDAR S3 is a compact scanning LiDAR built for reliable ranging and perception indoors or outdoors, even in bright daylight.

SLAMTEC’s SL-TOF direct time-of-flight design helps improve measurement accuracy and light immunity for mapping and obstacle detection.

A stable measurement radius up to 40 meters supports longer-range scanning for navigation, mapping, and environment perception.

Low-reflectivity performance helps maintain usable ranging on darker targets for more consistent obstacle detection.

High-speed 32 kHz sampling captures more points per second for smoother mapping and responsive obstacle avoidance.

Ambient-light resistance up to 80,000 lux helps keep scan data stable in sunlit spaces and bright indoor environments.

With an overall height around 4 cm, the sensor fits neatly into tight robotic enclosures and compact platforms.

Designed to integrate with the SLAMTEC ecosystem, it supports common interfaces for straightforward hardware and software integration.

The infrared light source meets IEC-60825 Class 1 laser safety requirements for typical use around people.

Typical applications include robot navigation, AGV obstacle avoidance, UAV mapping, parking/area monitoring, and ROS education projects.
