1. Product Description
The TFmini-S is a single-point ranging LiDAR module, an upgrade from the TFmini. It features a shortened blind zone of 10cm, improved outdoor performance, and enhanced accuracy across different reflectivity levels. This module is designed to achieve stable, accurate, sensitive, and high-frequency range detection.
Key characteristics of the module include:
- Small size
- Light weight
- Low power consumption
- High frame rate (up to 1000Hz)
Main application scenarios:
- Pedestrian detection
- Vehicle detection
- Intelligent barrier gate
- Altimeter
