Benewake TFS20-L is a high-performance, miniature  LiDAR module for precise distance measurement in the range of up to 20 m . Built on the basis of dToF technology and SPAD sensor , it enables accurate measurement even in difficult lighting conditions. Its ultra-compact design ( 21 x 15 x 7.87 mm ) and low weight ( 1.35 g ) make it perfect for integration with drones , mobile robots and IoT devices. The module supports UART and I2C interfaces, has a temperature compensation function and integrated operating modes, which allows you to adjust parameters to a specific application. TFS20-L is also resistant to strong light (up to 100 kLux) and achieves accuracy of ± 6 cm in the range of 0.2 to 6 m .

The module includes a highly sensitive SPAD sensor with infrared amplification with a range of up to 20 m.

Main features of the TFS20-L sensor

• Compact design : small dimensions of 21 x 15 x 7.87 mm and weight of only 1.35 g enable integration with drones, robots and compact IoT devices
• dToF technology and SPAD sensor : uses the laser beam time-of-flight measurement method and a highly sensitive SPAD sensor to ensure stable measurement
• Range up to 20 meters : allows you to measure distances up to 20 m with an accuracy of ± 6 cm (in the range from 0.2 m to 6 m) and 1% above 6 m
• Ambient light resistance : stable operation even in lighting conditions up to 100,000 lux - ideal for outdoor use
• Multi-protocol communication : supports UART (115200 bps) and I2C (up to 400 kbps) interfaces, facilitating integration with various microcontrollers
• Low power consumption : 3.3V DC power supply, power consumption less than 0.35W - ideal for battery operation
• High measurement frequency : can work with a reading frequency of up to 250 Hz - ideal for dynamic applications
• Class 1 Laser Safety : Meets EN60825 standard - safe for eyesight during standard use

Compact dimensions and low weight

The TFS20-L module has been designed for integration in applications with limited space. Its miniature dimensions (21 x 15 x 7.87 mm) and weight of only 1.35 g allow for a significant reduction in the overall weight of the device. This is especially important in drones and robots , where every gram counts for uptime and performance.

Precise measurement and wide range

TFS20-L offers exceptional measurement accuracy of ±6 cm in the range of up to 6 m and 1% above this value , providing reliable data in real time. Thanks to high resistance to light interference (up to 100 kLux), the module works stably both indoors and outdoors . Built-in temperature compensation and the ability to work with different degrees of light reflection ensure reliability in different conditions.

• Practical applications

  TFS20-L is used in UAVs (autonomous landing, maintaining altitude), mobile robots (fall prevention and obstacle detection), IoT systems (smart containers, doors and presence sensors), as well as in household appliances, home automation and industrial solutions . Versatility and the ability to adjust operating parameters make it suitable for both prototyping and finished products.
