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.

Detailed Descriptions

• UART / I2C

• I/O mode:

In I/O output mode, the detection information is indicated by the high and low levels of pin 6. When the output is near-zone level, the output switches to far-zone level after the measured value is greater than the far end point of the hysteresis interval; when the output is far-zone level, the output switches to near-zone level when the measured value is less than the near end point of the hysteresis interval. (High level: 3.3V, low level: 0V)
