2.3 Measuring principle
TF03 is a typical Pulse Time of Flight (PToF) sensor. TF03 emits a narrow pulse laser,
which is collimated by the transmitting lens, which enters the receiving system after being
reflected by the measured target and is focused on the APD detector by the receiving lens.
The time between the transmitted signal and the received signal is calculated through the
circuit amplification and filtering, and the distance between TF03 and the measured target
can be calculated through the speed of light.

2.4 Technical specification
NOTICE
TF03 has two versions, TF03-100 and TF03-180. The only difference between
the two versions is the maximum detecting range, which is 100m and 180m
respectively.
