TFMini-S - Micro LiDAR Module

The TFMini-S Micro LiDAR Module is a ToF (Time of Flight) LiDAR sensor capable of measuring the distance to an object as close as 10 centimeters (+/- 6cm up to 6m) and as far as 12 meters (+/-1% starting at 6m)! As with all LiDAR sensors, your effective detection distance will vary depending on lighting conditions and the reflectivity of your target object, but what makes this sensor special is its size. Measuring only 42x15x16mm, the TFMini-S allows you to integrate LiDAR into applications traditionally reserved for smaller sensors.

TFMini-S is a single-point ranging LiDAR based on TFmini upgrade. The blind zone is shortened to 10cm, the outdoor performance and accuracy of different reflectivity are improved, it can achieve stable, accuracy, sensitive and high frequency range detection.

Important: This product does not use laser light for ranging. Instead it contains an LED and optics. Many such systems are being marketed under the name "LiDAR," although it may be more appropriate to think of this device as a "Time-of-Flight Infrared Rangefinder". It differs significantly from traditional IR rangefinders in that it uses ToF to determine range and not triangulation — as is performed by the Sharp GP-series devices.

TFMini-S - Micro LiDAR Module Product Help and Resources

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    Is it possible to measure water levels with this module? (TFMini-S - Micro LiDAR). Thanks

  • Member #579398 / about 4 years ago * / 1

    What cables, and other accessories do I need to purchase with this TFMini-S to hook up to an arduino? Does it come with the data cable and 4 pin male jumper conversion cable shown in the product shot? Do I need the TTL to USB converter and the logic level converter if I'm using a board?

    • Pearce / about 4 years ago / 1

      The cables are included.

      Hi there, it sounds like you are looking for technical assistance. Please use the link in the banner above, to get started with posting a topic in our forums. Our technical support team will do their best to assist you.

      That being said... I'll try to ping the product catalog team about the cables. My guess is no, because they usually specify multiple items in an Includes tab. To answer your second question, yes you will need a TTL to USB converter or microcontroller to retrieve the data from the sensor.

      Update: I stand corrected, the cables are included.

Narrow beam

I plan to use the module to tell whether a door is open from some distance away. Thanks to the narrow detection cone, it works great! I happened to have just the right USB to serial converter, and all I had to do was connect red-to-red, black-to-black, white-to-green and green-to white to use the available test program.
