This product is based on ToF (Time of Flight) principle and integrated with unique optical and electrical designs, so as to achieve stable, precise, high sensitivity and high-speed distance detection.


ToF is the abbreviation of Time of Flight technology, and its operating principle is as follows: a modulated near-infrared light is sent from the sensor and reflected by an object; the distance to the object to be shot can be converted with the sensor by calculating the time difference or phase difference between the light sending and the light reflection, so as to produce the depth information.


Applications:

• Drone altitude holding and terrain following

• Machine control and safety sensor

• Robot distance detection


If you are using Seeeduino Lite then just put it straight into the Grove Serial Interfaces.

    Hi Dear Customer, The Grove-TF Mini LiDAR’s UART baud rate is 115200 and the SoftwareI2C can’t support it. So if we use 1 hardware UART to hook up the sensor and other hardware UART for Serial Port display, we need at least 2 hardware UART platforms, such as arduino mega, seeeduino lite and so on. If we only have 1 UART platform(ie. seeeduino v4.2, arduino uno), we can use the I2C LCD as display. Bill

    Hi again, The sensor is not in pixmode. See listing with the setupsequence. No commands for Enter/Exit configmode are used. (I also use setupcode to force middle distance mode. Not included in listing. ) Two Lidarsensors connected to a MEGA 2560 But I have to use a slight delay between each setupcommand. It works fine now. So I&#39;m happy. But it would be interesting to know why I can&#39;t follow the procedure described in manual ? Serial.println (&quot;Initializing...&quot;); // Step 2: Initialize the data rate for the SoftwareSerial port Serial1.begin(TFMINI_BAUDRATE); Serial2.begin(TFMINI_BAUDRATE); // Step 3: Initialize the TF Mini sensor tfminiLeft.begin(&amp;Serial1); tfminiRight.begin(&amp;Serial2); pinMode(10, INPUT_PULLUP); // Halt measurement pinMode(13, INPUT_PULLUP); // Unit cm or mm delay(100); tfminiLeft.setStandardOutputMode(); delay(100); tfminiRight.setStandardOutputMode(); delay(100); // Step 4: Initialize single measurement mode with external trigger tfminiLeft.setSingleScanMode(); delay(100); tfminiRight.setSingleScanMode(); delay(100); tfminiRight.setUnitOfDistanceTomm(); delay(100); tfminiLeft.setUnitOfDistanceTomm(); delay(100); }
