1. TFmini-i is a single-point ranging LiDAR upgraded from the TFmini-S. It features optimized enhancements in communication interfaces and input voltage to meet the demands of various industrial scenarios. Based on the ToF (Time of Flight) principle, the product delivers stable, precise, and highly sensitive measurement performance.
2. Working Principle: TFmini-i operates on the ToF (Time of Flight) principle. Specifically, the device periodically emits near-infrared modulated light waves, which reflect back upon hitting an object. The device calculates the relative distance between itself and the target by measuring the phase difference of the round-trip modulated waves to determine the time of flight.
3. Supports wide voltage input and RS-485 interface.
4. Application Scenarios: Pedestrian detection / Vehicle detection / Altimeter / Robotics.
