Description

The Benewake TFMini Micro LiDAR Distance Sensor utilizes a Time-of-Flight (ToF) principle, measuring the round-trip time of a modulated 850nm infrared light pulse to calculate distance. This solid-state design, free of moving parts, provides stable and reliable ranging performance in both indoor and outdoor environments up to 70,000 Lux ambient light.

Its integrated optical and electronic design results in a compact, lightweight module with low power consumption, making it ideal for battery-powered mobile applications. The sensor outputs precise distance data via a simple UART serial protocol, compatible with a wide range of 5V logic microcontrollers and flight controllers.

Frequently Asked Questions

What is the communication protocol for the TFMini sensor?

The TFMini communicates via a standard UART (Serial) interface. It transmits distance data as a structured packet of bytes, which can be easily parsed by microcontrollers like Arduino, Raspberry Pi, or flight controllers such as Pixhawk. The baud rate is typically configurable, with 115200 bps being a common default setting.

What is the operating voltage range, and can it run on 3.3V logic?

The sensor requires a supply voltage between 4.5V and 6.0V DC. While the power supply must be within this 5V nominal range, the UART signal lines are 3.3V tolerant. This means you can interface it directly with 3.3V logic microcontrollers without requiring a level shifter for the data lines.

How accurate is the TFMini sensor, and what affects its performance?

Accuracy is 1% of the measured distance for targets within 0.3 to 6 meters, and 2% for distances between 6 and 12 meters. Performance can be affected by extreme ambient light (beyond 70,000 Lux), highly reflective or absorbent target surfaces, and objects within the narrow 2.3° acceptance angle but outside the minimum 0.3M range.

Is this sensor suitable for outdoor drone applications?

Yes, the TFMini is designed with algorithms adapted for both indoor and outdoor environments. Its high ambient light tolerance (up to 70,000 Lux) and robust ToF principle make it suitable for applications like drone obstacle avoidance, terrain following, and assisted landing in varying light conditions.
