Adafruit VL6180X Time of Flight Distance Ranging Sensor (VL6180)

by Adafruit

The VL6180X (sometimes called the VL6180) is a Time of Flight distance sensor like no other you've used!

The sensor contains a very tiny laser source, and a matching sensor. The VL6180X can detect the "time of flight", or how long the laser light has taken to bounce back to the sensor. Since it uses a very narrow light source, it is good for determining distance of only the surface directly in front of it.

Unlike sonars that bounce ultrasonic waves, the 'cone' of sensing is very narrow. Unlike IR distance sensors that try to measure the amount of light bounced, the VL6180X is much more precise and doesn't have linearity problems or 'double imaging' where you can't tell if an object is very far or very close.

This is the 'little sister' of the Adafruit VL53L0X ToF sensor, and can handle about 5mm to 100mm of range distance. We've seen up to 150-200mm with good ambient conditions. It also includes a lux sensor. If you need a larger range, check out the VL53L0X which can measure 50 - 1200 mm.

The sensor is small and easy to use in any robotics or interactive project. Since it needs 2.8V power and logic we put the little fellow on a breakout board with a regulator and level shifting. You can use it with any 3-5V power or logic microcontroller with no worries. Works great with the 3.3V logic level of a Feather or Raspberry Pi, or the 5v level of a Metro 328 or Arduino Uno, this breakout is ready to work with most common microcontrollers or SBCs. and since it speaks I2C, you can easily connect it up with two data wires plus power and ground. 

As if that weren't enough, Adafruit also added SparkFun qwiic compatible STEMMA QT connectors for the I2C bus so you don't even need to solder. Just wire up to your favorite micro with a plug-and-play cable to get 6-DoF data ASAP. For a no-solder experience, just wire up to your favorite micro, like the STM32F405 Feather using a STEMMA QT adapter cable.

Each order also comes with a small piece of header. Solder the header onto your breakout board with your iron and some solder for when you want breadboard or perfboard friendliness.

Check out the tutorial for code, schematics, diagrams and more! You'll be rangin' in less than 10 minutes. Communicating to the sensor is done over I2C with some simple commands. Most of the work is handled inside the sensor itself, so its very easy to port our Arduino library to another microcontroller.

TECHNICAL DETAILS

  • Schematics, Fritzing object, diagrams, interface code and more in the tutorial!
  • Revision History:
    • As of March 3, 2020 - We've updated this sensor to our 0.7" x 1.0" STEMMA QT standard for sensors. There are now four mounting holes and two STEMMA QT connectors for plug-and-play connectivity! The schematic is the same, only the mechanical shape has changed, we also removed the 2.8V output pin.
