Benewake TFmini Plus Single-Point Ranging LiDAR Modules

Benewake TFmini Plus Single-Point Ranging LiDAR Modules provide a low-cost, small-size, and low power consumption solution to promoting cost-effective LiDARs. The TFmini Plus modules improve frame rate, optimize various compensation algorithms, and are packaged in an IP65 rated enclosure. The devices are compatible with both UART and I2C interfaces that can be switched by commands. The TFmini Plus LiDAR Modules emit modulation waves of near-infrared rays on a periodic basis, which will be reflected after contacting the object. The time of flight is then measured by the round-trip phase difference and then the relative range is calculated between the product and the detection object. They are ideal for stable, accurate, and high-frequency range detection.
