TFS20-L 20m ToF LiDAR Sensor Sunlight Resistant

The TFS20-L from Benewake is an ultra-compact dToF LiDAR sensor for precise distance measurements up to 20 meters. The module integrates a highly sensitive, infrared-enhanced SPAD sensor and operates on the direct Time of Flight (dToF) principle. With dimensions of only 21 × 15 × 7.87 mm and a weight of only 1.35 g, the sensor is ideal for weight-sensitive applications such as drones and mobile robots. Communication is optionally via UART or I²C, allowing flexible integration into various microcontroller platforms such as Arduino, ESP32, and Raspberry Pi.

Features:

Ultra-light design with only 1.35 g weight does not affect flight time and agility
Measurement range up to 20 meters allows extensive distance detection at 90% reflectivity
Sunlight resistance of 100 Klux ensures stable measurements outdoors
Configurable frame rate up to 250 Hz supports fast real-time obstacle detection
Dual interfaces with UART and I²C offer flexible integration options
Class 1 laser safety according to EN60825 enables safe use in end applications

Application examples:

Drone altitude hold and terrain following systems for autonomous flights
Robotics crash protection and edge detection for mobile platforms
Obstacle detection for autonomous vehicles and AGVs
Presence detection in smart home applications and IoT devices
Level measurement in industrial containers and silos
