TF03 Laser Range Sensor

SKU: SEN0328

TF03, the 3rd-gen TF series laser range sensor, offers 100m/180m detection ranges. Compact (44×42.9×31.8mm) with pulsed ToF principle, it has ±10cm accuracy, 0.1m blind zone, 10KHz frequency, and 100Klux ambient immunity. IP67-rated, it supports UART/CAN/IO, configures parameters, and works with Arduino/Raspberry Pi. Applications include drone terrain following, car collision avoidance, etc.

    • 1. Getting Started

    This project includes a PC-based example that demonstrates how to connect the TF Mini laser ranging sensor to a computer using a USB-to-TTL converter and display real-time distance measurements with the provided PC software, as well as important usage notes for the sensor.
    2. Example Code for Arduino-Distance Measurement

    Use Arduino Uno with software serial to read distance and signal strength from TF03, and display the results on a PC serial port tool.

    3. Example Code for Arduino-LCD Distance Display

    In this tutorial, an Arduino Uno reads distance and signal strength from the TF03 sensor and displays the data on an RGB LCD. The entire system is powered by a Li-ion battery, allowing it to operate without a PC.
    4. Example Code for Arduino-Black and White Line Detection

    The TF Mini laser ranging sensor is susceptible to surface reflectivity, making it suitable for close-range black-and-white line detection. By comparing the TF03’s signal-strength output, the system can easily differentiate white (high reflectivity) from black (low reflectivity).
    5. Example Code for Raspberry Pi-Distance Measurement

    This project shows how to connect the TF03 laser range sensor to a Raspberry Pi via UART and read real-time distance and signal-strength data using Python.

    The interface type of the product is MH1.25-7P, which cannot be directly used with an Arduino Uno. Therefore, we provide 2.54 mm single-pin Dupont wires and a PH-P connector housing. Connect the sensor wires to the Dupont wires as follows:

    • black (sensor) → black (Dupont)
    • red → red
    • brown → blue
    • yellow → green

    The sensor supports two communication modes: TTL and CAN. The default mode is TTL, and it can be changed via command. Please note that the two modes cannot be enabled at the same time.
