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.
