TFmini-i LiDAR is an industrial-grade medium-range distance sensor. Its maximum detection range can reach up to 12m and it has an adjustable frame rate with a maximum of 1KHz.

This rangefinder has a PC/ABS/PMMA enclosure with IP65 water and dust resistance. It supports a wide range of input voltages (7-30V) with reverse protection to protect the internal circuit and adopts RS485 communication interface and standard Modbus protocol. Multiple built-in operating modes are included for the users to change their parameters and configurations to meet different applications.

The TFmini-i LiDAR 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 single point 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.
