Great value, minor setup learning curve
The sensor works exactly as described. It took me a little while to configure the baud rate correctly with my Arduino, but once set up, the distance readings are consistent and fast.

Good performance in normal light
Works great inside and in shaded outdoor areas. I noticed some noise in direct bright sunlight, which is expected for this type of sensor, but overall very satisfied with the purchase.

Perfect for obstacle avoidance
Integrated this sensor into my custom drone project for low-altitude hovering. The data is stable and the small form factor made mounting very easy. Highly recommended for DIY robotics.

Excellent documentation support
The hardware is solid, and the protocol documentation provided by Benewake made integration with my Raspberry Pi straightforward. No issues after two weeks of continuous testing.

Compact and powerful
I was surprised by how small this unit is compared to older lidar modules. It fits perfectly in tight spaces on my rover chassis. The cable connection is secure.

Reliable for indoor mapping
We used several of these for a university robot navigation project. They perform well in indoor lighting conditions and the update rate is sufficient for real-time processing.
Q: Is there a library available for Arduino?
A: Yes, there are several open-source libraries available on GitHub specifically for the TFmini and TFmini-S series that simplify distance reading and configuration on Arduino platforms.
Q: Does this module work directly with 3.3V logic levels?
A: The TFmini-S operates at 5.0V. While the TX pin is 3.3V tolerant, the RX pin requires 5.0V logic. We recommend using a logic level converter if your microcontroller runs on 3.3V.
Q: Can this sensor measure through glass?
A: No, laser ToF sensors generally cannot measure distance through transparent materials like glass because the laser beam passes through rather than reflecting back. It may also produce erratic results on highly reflective surfaces.
Q: What is the maximum sampling frequency achievable?
A: The standard sampling frequency is 100Hz, but it can be configured up to 1000Hz via the serial command interface depending on your application needs.
Q: What happens if the object is closer than 0.3 meters?
A: If an object is detected within the blind zone (less than 0.3m), the sensor will output a specific error code or invalid distance value as defined in the communication protocol manual.
