Upgrade drone or robot with the Benewake TFS20-L ToF LiDAR sensor. Get precise, centimeter-level distance measurement up to 20 meters, even in challenging 100Klux direct sunlight. Weighing just 1.35g and smaller than a thumbnail, it delivers high-frequency data (up to 250Hz) without impacting your design's weight or balance. It's the perfect high-performance, drop-in solution for UAV altitude hold, robot anti-drop functionality, and reliable obstacle avoidance.
Feather-light & Fingernail-Sized
Weighing a mere 1.35g and with dimensions of just 21x15x7.87mm, it adds powerful sensing without impacting your drone's flight time or robot's agility.
Exceptional Outdoor Performance
Engineered with 100Klux ambient light resistance, it provides stable and accurate measurements outdoors, even in bright sunlight where other sensors fail.
Long-Range & High-Frequency Sensing
Measures distances up to 20 meters with a configurable frame rate up to 250Hz, enabling real-time navigation and rapid obstacle detection.
Flexible I2C & UART Interfaces
Choose the best communication protocol for project. Easily integrate with virtually any microcontroller, from Arduino and ESP32 to Raspberry Pi.
Fully Integrated & Ready-to-Use
With a built-in power module and temperature compensation, this sensor works reliably out of the box on a simple 3.3V supply, saving development time.
Class 1 Eye-Safe Laser
The 905nm VCSEL light source is certified Class 1, ensuring safety for development, demonstration, and end-user applications.
