Small Size & High Performance
Inheriting the advantages of the TFmini's small size. This ToF Single-Point Ranging Sensor is only 50mm*34mm*41mm , but it brings us excellent performance and can be flexibly and easily integrated into various small smart devices.
Easy to Use
The TFmini-i ToF single-point ranging sensor can be used on the Arduino UNO R3 through the TTL to RS485 Shield,
and it can also be used on the Raspberry Pi through the USB to RS485 module.
Those two ways provided by DFRobot can make TFmini-i LiDAR easier to use.
How does TFmini-i LiDAR work?
TFmini-i is a TOF single point solid state LiDAR, which is based on Pulse Time of Flight (PTOF).
It adopts an incoherent energy receiving mode, and the detection is mainly based on Pulse counting.
TFmini-i emits a narrow pulse laser, which is collimated by the transmitting lens to form a collimated light,
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 TFmini-i and the measured target can be calculated through the speed of light.
