youyeetoo YDLIDAR GS2 Solid State Lidar Sensor
The GS2 solid state lidar from youyeetoo offers a wide 100° field of view with two wavelength options, 808 nm and 850 nm. This design reduces blind spots in robot scanning and provides robust obstacle avoidance within a compact package. The system supports two wavebands without cross-interference, which can be useful in multi-sensor setups. Its detection range spans from 25 mm to 300 mm, making it suitable for close-range proximity sensing and collision avoidance on small robots or automated devices. A notable feature is its ability to detect very small objects, including objects as small as 3 mm in diameter, enhancing safety in tight environments.
Key considerations include its solid-state reliability, small form factor, and the potential benefits of having two wavebands. For best results, integrate GS2 where precise close-range sensing and a relatively broad field of view are needed, such as indoor mobile robots, AGVs, or smart devices requiring tight obstacle detection.
TOFFUTURE Single Point Lidar 0.3-30m
This TOFFUTURE lidar uses Time of Flight (TOF) principles with a 940 nm VCSEL light source. It offers a broad 0.3–30 m range and supports UART and I2C communications, allowing easy integration with common microcontrollers and single-board computers such as STM32, Raspberry Pi, and Arduino. The unit can be configured as an IO side device to indicate whether objects exist within a specific threshold. Its high-speed, high-precision ranging makes it suitable for compact robots, proximity sensing, and simple obstacle avoidance tasks in indoor environments.
In practice, TOFFUTURE’s compact form factor and dual-interface capability streamline implementation in hobbyist and professional projects. Expect straightforward integration, reliable single-point distance data, and flexible configurability in varied indoor settings.
youyeetoo TF02-Pro Single-Point Ranging Lidar
The TF02-Pro from youyeetoo provides single-point ranging with up to 40 meters of reach and high accuracy. It supports UART and I2C, making it versatile for drone, robotics, and industrial sensing applications. Its compact size (approximately 69 x 41.5 x 26 mm) and light weight (about 50 g) facilitate easy mounting on small platforms. The sensor is designed to resist common environmental interferences and maintains stable performance in various lighting conditions. It is well-suited for real-time distance measurement and rapid proximity checks in compact systems.
Consider TF02-Pro when you need a reliable single-point distance readout with broad compatibility and easy integration into microcontroller-led projects, mobile robots, or IoT sensing platforms requiring precise 2D distance data.
WayPonDEV SSL-20N Solid State Lidar
The SSL-20N from WayPonDEV is a solid-state lidar with a 110° field of view and an effective 30–400 mm range. It emphasizes real-time detection and dynamic obstacle avoidance, helping to reduce navigation blind spots when approaching furniture or other small obstacles. Its design includes strong anti-glare performance and robust filtering to minimize ambient light interference, enabling more reliable operation in bright indoor environments. The device supports UART and I2C interfaces for flexible integration into autonomous platforms and microcontroller-based systems.
Ideal for compact robots and indoor mapping tasks, SSL-20N balances a wide viewing angle with practical short-range sensing. Its compact footprint and fast update rates make it a practical choice for obstacle avoidance in service robots, educational kits, and small automated appliances.
Wishiot TF-Luna LiDAR Range Finder
The TF-Luna from Wishiot is a compact, single-point ranging LiDAR module designed for Arduino, Raspberry Pi Pico, Pixhawk, and similar platforms. Its sensing range spans 0.2–8 meters with a 1 cm resolution and very low power consumption. It uses UART by default and can be configured for I2C communication. The tiny form factor and light weight make TF-Luna ideal for lightweight drones, small robots, and educational kits that require precise short-range sensing with straightforward wiring. The 0.96″ OLED display example in the product description hints at easy telemetry and debug readiness for hobbyists and educators.
TF-Luna’s strength lies in simple integration and consistent short-range performance. When exact measurements are needed at close distances in compact builds, this module provides a reliable, low-cost option with broad compatibility across popular platforms.
Buying Guide: Key Purchase Considerations And Comparisons
Choosing the right solid state lidar sensor involves balancing range, field of view, accuracy, and integration ease. Consider these perspectives to determine which model best fits your project.
- Range and resolution: Short-range modules like GS2 and TF-Luna excel in obstacle avoidance and precise close-range sensing, while single-point devices such as TF02-Pro and TOFFUTURE variants offer broader distance coverage for scanning or mapping tasks.
- Field of view: A wider FOV, as seen in the GS2 and SSL-20N, helps detect obstacles from more angles, reducing blind spots. Narrow FOV units can offer higher precision at a specific direction, which is useful for targeted distance sensing.
- Interfaces and compatibility: UART and I2C are common, but check device-specific requirements and your microcontroller ecosystem (Raspberry Pi, STM32, Arduino, Pixhawk, etc.). Multi-interface devices enable flexible integration.
- Robustness and environment: IP ratings, operating temperature ranges, and resistance to ambient light are important for outdoor or bright indoor settings. Modules with better filtering and rugged housings tend to perform more reliably in real-world conditions.
- Form factor and mounting: Smaller sensors simplify integration into compact robots or vehicle bumpers. Consider weight, size, and fixation options when planning installation.
- Safety and standards: Some models comply with eye-safety standards (FDA Class 1), which may influence usage in spaces with people or pets nearby.
- Cost vs. performance: For hobby projects, a TF-Luna or TOFFUTURE module provides good baseline performance. For more demanding navigation tasks, a wider-FOV option with robust filtering may justify higher costs.
- Power consumption and heat: In battery-powered devices, low power draw extends runtime. Review current draw specifications and thermal behavior under load.
In summary, for close-range obstacle avoidance in compact robots, GS2, SSL-20N, and TF-Luna offer practical blends of range, field of view, and ease of use. For broader distance sensing and flexible interfaces, single-point lidar options like TOFFUTURE and TF02-Pro can be integrated into a wider sensing stack. Always validate compatibility with your hardware, firmware, and software libraries before committing to a specific module.
