Description

The CS20 utilizes a 940nm VCSEL-based Time-of-Flight (ToF) imaging sensor to capture detailed three-dimensional spatial information. Its solid-state design ensures reliability with no moving parts, offering advantages over structured-light systems, including smaller blind spots, distance-linear error correlation, and strong environmental adaptability. The sensor outputs synchronized depth and amplitude data, enabling precise point cloud generation for complex 3D modeling and navigation tasks.

Designed for continuous operation in indoor environments, the CS20 operates within a -10°C to 50°C temperature range. Its compact form factor (48x34x12 mm) and USB Type-C connectivity simplify integration into robotic platforms, interactive systems, and security setups, providing a high-value solution for accurate depth sensing without the high cost typically associated with commercial ToF cameras.

Key Features

  • High-Resolution ToF Sensor: Features a 640x480 resolution ToF image sensor for detailed depth mapping, with a configurable lower resolution mode (320x240) for faster frame rates.
  • Millimeter-Level Measurement Accuracy: Delivers precise distance data critical for applications like robotic navigation and volume measurement.
  • Optimized Performance-to-Cost Ratio: Provides excellent 3D imaging capabilities and measurement precision in a cost-effective solid-state package.
  • Low Power Consumption: Average power dissipation of only 1.2W (5V @ 0.5A) enables use in battery-powered or energy-conscious systems.
  • USB 2.0 Type-C Interface: Single-cable solution for both 5V power supply and high-speed data transmission, simplifying system wiring.
  • Adjustable Frame Rate & Range: Offers configurable operational parameters via SDK to optimize performance for specific application needs.
  • Class 1 Laser Safety: Eye-safe operation ensures safe use in a wide variety of environments and applications.
  • Robust Environmental Adaptability: Performance is not significantly degraded by scene texture or ambient light variations, unlike structured-light systems.

Applications

  • Robotic SLAM & Navigation: Provides real-time 3D depth data for autonomous robot mapping and obstacle avoidance in indoor environments.
  • Precision Volume Measurement: Accurately calculates the dimensions and volume of objects for logistics and inventory management.
  • Interactive Systems & Gesture Recognition: Enables somatosensory interaction and gesture-based control for kiosks, gaming, and AR/VR interfaces.
  • 3D Scanning & Modeling: Captures detailed point clouds for creating 3D models of objects or environments.
  • Security Monitoring & People Counting: Facilitates intelligent surveillance and occupancy monitoring in retail spaces or secure areas.

Frequently Asked Questions

What is the power requirement for the CS20 ToF LiDAR sensor?

The CS20 requires a 5V DC power supply, typically drawing 0.5A, for a total average power dissipation of 1.2W. Power is supplied exclusively through its integrated USB Type-C connector, which also handles all data communication, eliminating the need for a separate power cable.

How do I interface with the CS20 sensor and get depth data?

Communication is via the USB 2.0 Type-C interface. DFRobot provides a Software Development Kit (SDK) for Linux, Windows, ROS, and Android platforms. Using this SDK, you can access raw depth frames, point cloud data, signal amplitude, and configure parameters like resolution (640x480 or 320x240) and frame rate.

What is the effective measurement range and accuracy of the CS20?

The sensor has a typical indoor measurement range of 0.1 to 5 meters against a white wall target. It achieves millimeter-level measurement accuracy within this range. Performance is optimized for indoor use and may vary with target reflectivity and ambient light conditions.

Can the CS20 be used outdoors or in bright sunlight?

The CS20 is primarily designed for indoor applications. Its 940nm VCSEL source provides good ambient light robustness, but direct, bright sunlight (which contains strong 940nm components) can saturate the sensor and degrade performance. For reliable outdoor operation, shading or operation in shaded conditions is recommended.

What is included in the package, and are any cables provided?

The package includes the CS20 LiDAR sensor module itself. A USB Type-C cable is not included; you will need to provide a standard USB Type-C cable capable of supporting USB 2.0 data and 5V power delivery to connect the sensor to your host computer or controller.
