Time of Flight Distance Sensor VL53L4CD

The Adafruit VL53L4CD Time-of-Flight Distance Sensor is ideal for accurate distance measurements. The sensor delivers stable results from approximately 1.0 mm to 1300.0 mm with high repeatability. Thanks to its narrow measuring beam, it is ideal for robotics, obstacle detection, automatic measurements or interactive installations. 
 It has a STEMMA QT / Qwiic connector for easy plug-and-play connections without soldering. 
 
 
 
 
 Measuring range from approximately 1.0 mm to 1300.0 mm 
 Compatible with 3.3V and 5V 
 Narrow beam (FoV approx. 18 degrees) for precise detection 
 STEMMA QT / Qwiic connector for easy connection 
 Fast measurements up to about 100 Hz

 Sensor:  Adafruit VL53L4CD Time of Flight Distance Sensor 
 Cable: STEMMA QT / Qwiic JST SH 4-pin to Premium Male Headers Cable 
 Arduino UNO (other models also are fine) × 1 + power cable (sold seperately) 
 
 
 
 
 2 Assembly 
 
 Wire  using the STEMMA QT connector. If you are using a 3V board, like an Adafruit Feather, wire the board's 3V pin to the VL53L4CD VIN. 
 
 Board 5V to sensor VIN (red wire) 
 Board GND to sensor GND (black wire) 
 Board SCL to sensor SCL (yellow wire) 
 Board SDA to sensor SDA (blue wire) 
 
 
 3 Software & code 
 In the Arduino software Click the  Manage Libraries ... menu item (under Tools), search for  VL53L4CD , and select the STM32duino VL53L4CD library. Install it. 
 The library comes with some example sketches, I used one of them and adjusted the code so the useless information like status, signal, tekst is removed. It now only outputs a stream of values. 
 Open a new arduino file ande replace the code with this: 
 
 #include <Arduino.h> 
 #include <Wire.h> 
 #include <vl53l4cd_class.h> 
 
 #define DEV_I2C Wire 
 
 VL53L4CD sensor (&DEV_I2C, A1); 
 
 void setup () { 
 Serial . begin ( 115200 ); 
 Wire . begin (); 
 
 sensor . begin (); 
 sensor . VL53L4CD_Off (); 
 sensor . InitSensor (); 
 
 // Hoge nauwkeurigheid 
 sensor . VL53L4CD_SetRangeTiming ( 200 , 0 ); 
 
 // Start met meten 
 sensor . VL53L4CD_StartRanging (); 
 } 
 
 void loop () { 
 uint8_t dataReady = 0 ; 
 VL53L4CD_Result_t results; 
 
 // Wacht tot er nieuwe data is 
 do { 
 sensor . VL53L4CD_CheckForDataReady (&dataReady); 
 } while (!dataReady); 
 
 // reset interrupt 
 sensor . VL53L4CD_ClearInterrupt (); 
 
 // meetresultaat ophalen 
 sensor . VL53L4CD_GetResult (&results); 
 
 // alleen afstand printen 
 Serial . println ( results . distance_mm ); 
 
 } 
 
 
 5 Connect the arduino to your computer.  
 Connect Arduino to your computer & Upload the code. If you do not know how to upload a Arduino sketch, please visit https://www.arduino.cc/en/Guide/Windows for Windows user or https://www.arduino.cc/en/Guide/MacOSX for Mac user. Open the serial monitor by clicking the Magnifying glass in the top right corner of the window. You might need to change the Baud rate to: 115200 before you get good results. Do this in the top right of the serial monitor field. You should now see a stream of data measuring the distance to the object in front of the sensor. Hold your hand in front of the sensor and move it.
