TFmini-i Medium-Range Distance Detection Sensor

SKU: SEN0505

TFmini-i LiDAR is an industrial-grade medium-range distance sensor with a 12m max detection range, adjustable frame rate up to 1KHz, IP65-rated PC/ABS/PMMA enclosure, 7-30V input (reverse protection), RS485 interface, Modbus protocol, and multiple built-in modes. It works with Arduino UNO R3 (TTL to RS485 Shield) and Raspberry Pi (USB to RS485 module) via DFRobot’s simplified methods.
