Introduction

TFmini-S LiDAR Sensor is an upgrade project based on TFmini, which is a miniaturized, single-point distance measurement product based on the ToF (Time of Flight) principle with unique optical, electrical, and algorithm design, mainly to achieve stable, accurate, high sensitivity and high-speed distance measurement functions. In addition to the low cost, small size, and long-range of TFmini, the product has higher range accuracy, better adaptability to different environments such as outdoor bright light, different temperatures, and different reflectivity, lower power consumption, and more flexible detection frequency. The product is compatible with both UART and I2C communication interfaces and can be switched by command.
