    Description

    Autonomous Vehicle is getting serious lately and LiDAR (Light Detection and Ranging), now we carry this affordable LiDAR sensor. The TF Mini LiDAR is a unidirectional laser range finder based upon time-of-flight (ToF) technology. It consists of special optical and electronic devices, which integrates adaptive algorithm for the indoor and outdoor application environment. It has a tiny body and high performance in distance measurement. 

    The laser sensor can be used as a distance-measuring tool to detect the distance from it to obstacles. It can also be used as an eye of a robot; it provides distance information for robotic safe avoidance and route selection. It supports system automation in a variety of machine control scenarios. Because of its small size, lightweight, and low power consumption, it is also suitable for altitude-hold quad-copters and terrain following.

    TF Mini's maximum detection distance is 12 meters. TF Mini also supports 100Hz sampling resolution, within 6 meters, its accuracy is within 4cm, 6~12 meters, and accuracy is within 6 cm. FOV of 2.3 degrees. Its anti-interference is strong, and can work in outdoor light; the overall weight is 4.7g.


    Measurement range schematic diagram


    TF Mini LiDAR adopts UART (TTL) communication interface, can supply with standard 5VDC, and its average power consumption is 0.6W. It is compatible with a variety of Arduino controllers. Just ensure the wiring of power and UART are correct.

    It can be easily integrated into the system when used with the Arduino library.


    NOTE:

    • The product may be invalid when probing objects with high reflectivities, such as mirrors and smooth tiles.
    • When there are transparent objects, such as glass and water, between the product and the tested object, it may become invalid.
    • Do not touch the circuit board with your bare hands. If necessary, please wear an electrostatic wristband or antistatic gloves.
    • Not recommended for measuring the level of liquids. This is because LiDAR relies on the reflection of laser pulses off of solid objects to determine distance, and liquid surfaces are often too smooth and reflective to produce a reliable reflection.

    Applications:

    • Machine control and safety measurement systems
    • Laser range finder robot
    • Altitude holds quad-copters and terrain following
