## Description

The TOFSense F2 is a high-performance, mid-range laser distance sensor based on dTOF (Direct Time-of-Flight) technology, offering the perfect balance of range (25m), speed (100Hz), and precision (±3cm). Designed for industrial automation, robotics, and smart traffic systems, it delivers reliable, real-time distance measurements even in challenging lighting conditions (100K LUX resistance). With UART, I2C, and I/O interface support, it integrates seamlessly into embedded systems, drones, and automated guided vehicles (AGVs).

**25m Mid-Range Detection with ±3cm Accuracy**

The TOFSense F2 provides high-precision distance measurements up to 25m, making it ideal for industrial automation (e.g., conveyor belt tracking, bin level monitoring) and robotic navigation (e.g., AGV obstacle avoidance). With ±3cm accuracy and 1mm resolution, it ensures reliable data for positioning, object counting, and smart traffic systems.

**100Hz High-Speed Data for Real-Time Control**

With a 100Hz refresh rate, the F2 delivers instantaneous distance updates, critical for fast-moving applications like drone stabilization, dynamic robot path planning, and vehicle speed detection. Unlike slower 50Hz sensors, it minimizes latency in time-sensitive operations.

**100K LUX Ambient Light Resistance**

Engineered for outdoor and industrial environments, the F2 maintains stable performance under direct sunlight (100K LUX) and artificial lighting. This makes it suitable for smart traffic monitoring, outdoor drones, and construction site automation where lighting conditions vary.

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

The F2 supports UART, I2C, and I/O interfaces, offering flexible connectivity for microcontrollers, PLCs, and custom hardware. The I/O trigger function allows synchronization with cameras or other sensors, making it ideal for multi-sensor fusion systems.
