converted with the sensor by calculating the time difference or phase difference between the light sending and
the light reflection, so as to produce the depth information.

The object to be detected has 10% reflectivity and the effective detection distance is 5m;
Outside conditions:
Under the general sunshine condition (with illumination of lower than 70klux), the effective detection
distance is 7m;
Under the high sunshine condition in summer (with illumination of above 100klux) or the condition with
outdoor black background board, the effective detection distance is 3m.
Note: All distance parameters are set under the opposite direction with the object to be detected.

Note: The detection range side length is not equal to the object resolution ratio at the corresponding distance.
6. Serial Port Data Communication Protocol and Line Sequence
The following section describes the connections and communications between TF_mini and external devices,
including the encoding format of the sending data, the communication protocol between the module and the
external devices, the hardware line connection indications, and the related precautions.
Data bit 8
Stop bit 1
Parity bit 0
Dist_L distance value is a low 8-bit. Note: The distance value is a hexadecimal value, for
Byte3
example, Distance 1,000cm = 03 E8 (HEX)
Checksum parity bit is a low 8-bit, Checksum = Byte1 + Byte2 + ... + Byte8, Checksum is
Byte9
the sum of the first 8 bytes of actual data; here is only a low 8-bit.
