Grove - Time of Flight Distance Sensor VL53L0X


Grove - Time of Flight Distance Sensor-VL53L0X is a high speed, high accurary and long range distance sensor based on VL53L0X.

The VL53L0X is a new generation Time-of-Flight (ToF) laser-ranging module housed in the smallest package on the market today, providing accurate distance measurement whatever the target reflectances unlike conventional technologies. It can measure absolute distances up to 2m, setting a new benchmark in ranging performance levels, opening the door to various new applications.

The VL53L0X integrates a leading-edge SPAD array (Single Photon Avalanche Diodes) and embeds ST’s second generation FlightSenseTM patented technology.

The VL53L0X’s 940 nm VCSEL emitter (VerticalCavity Surface-Emitting Laser), is totally invisible to the human eye, coupled with internal physical infrared filters, it enables longer ranging distances, higher immunity to ambient light, and better robustness to cover glass optical crosstalk.

Platforms Supported

Arduino Raspberry Pi BeagleBone Wio LinkIt ONE

Caution

The platforms mentioned above as supported is/are an indication of the module's hardware or theoritical compatibility. We only provide software library or code examples for Arduino platform in most cases. It is not possible to provide software library / demo code for all possible MCU platforms. Hence, users have to write their own software library.

Getting Started

Note

If this is the first time you work with Arduino, we strongly recommend you to see Getting Started with Arduino before the start.

Note

1 Please plug the USB cable gently, otherwise you may damage the port. Please use the USB cable with 4 wires inside, the 2 wires cable can't transfer data. If you are not sure about the wire you have, you can click here to buy

2 Each Grove module comes with a Grove cable when you buy. In case you lose the Grove cable, you can click here to buy

  • Step 1. Connect Grove - Time of Flight Distance Sensor to port IIC of Grove-Base Shield.

  • Step 2. Plug Grove - Base Shield into Seeeduino.

  • Step 3. Connect Seeeduino to PC via a USB cable.

Note

If we don't have Grove Base Shield, We also can directly connect Grove - Temperature and Humidity Sensor Pro to Seeeduino as below.

Software

  • Step 1. Download the VL53L0X Library from Github.

  • Step 2. Extract the Grove-Ranging-sensor-VL53L0X-master.zip file into the Arduino library folder.

Note

For example, I download this library into D:\Software\WorkWork\arduino-1.8.5\libraries,so only need to extract the zip file here. All in all, please make sure the Grove-Ranging-sensor-VL53L0X-master folder is in your Arduino library folder, like the picture below.

  • Step 3. Open the Grove-Ranging-sensor-VL53L0X-master\examples folder you've just extracted, you will see five subfolders:

Choose different example according to your own needs. Then double click the xxx.ino file to open the Arduino IDE.

Attention

We use high_accuracy_ranging.ino in this demo.

  • Step 4. Upload the demo. If you do not know how to upload the code, please check How to upload code.

  • Step 5. Open the Serial Monitor of Arduino IDE by click Tool-> Serial Monitor. Or tap the Ctrl+Shift+M key at the same time. if every thing goes well, you will get the result.

The result should be like:
