Benewake Tfmini-s Vs. Competitors: In-depth Comparison Of Specs, Performance, And Price

Benewake TFmini-S Information

Benewake TFmini-S is a small, low-cost, and high-performance time-of-flight (ToF) LiDAR sensor. It is based on the principle of optical radar, emitting a laser pulse and then measuring the time it takes for the reflected pulse to return. This allows the TFmini-S to accurately measure the distance to objects within a range of 0.1 to 12 meters.

The TFmini-S is a versatile sensor that can be used in a variety of applications, including robotics, drones, SLAM, and 3D mapping. It is also relatively easy to use, with a simple UART interface that can be connected to a variety of microcontrollers and development boards.
