**50m Long-Range & ±3cm High Precision**

The TOFSense F2P delivers best-in-class 50m detection capability, making it ideal for demanding applications like drone altitude hold, terrain mapping, and traffic monitoring. With ±3cm accuracy across its entire range, it ensures reliable measurements even at maximum distance, while its 1mm resolution enables fine-detailed tasks such as stockpile volume scanning and industrial inventory management. This combination of long-range and high precision sets it apart for professional-grade deployments where distance and reliability are critical.

**100Hz High-Speed Refresh Rate**

With an ultra-fast 100Hz refresh rate, the F2P provides real-time responsiveness for dynamic environments. This high-speed data output is essential for drone obstacle avoidance systems that require instantaneous reaction times, as well as smart traffic applications where accurate vehicle speed tracking and parking detection are crucial. The rapid updates ensure seamless performance in fast-moving scenarios, giving users a competitive edge in time-sensitive operations.

**Unmatched Ambient Light Resistance (100K LUX)**

Engineered to thrive in harsh conditions, the F2P operates flawlessly under direct sunlight (100K LUX) and high-intensity artificial light, making it uniquely suited for outdoor, industrial, and urban environments. Unlike conventional sensors that falter in bright settings, its advanced optics and algorithms maintain stable performance—whether deployed in sunlit construction sites, highway traffic gantries, or drone-based aerial surveys.

**Multi-Interface Support (UART / I2C / I/O)**

Designed for seamless integration, the F2P supports UART, I2C, and I/O interfaces, offering flexibility for embedded systems, PLCs, and custom hardware setups. The I/O trigger function allows synchronization with external devices like cameras or additional sensors, enabling synchronized data capture in multi-sensor arrays. This versatility makes it a go-to solution for developers needing plug-and-play compatibility across diverse architectures.
