Adafruit VL6180X Time of Flight Distance Ranging Sensor (VL6180)

The Adafruit VL6180X is a close-range Time-of-Flight (ToF) distance sensor from ST that measures from approximately 5 mm to 100 mm (up to 150–200 mm in good conditions). It also includes a built-in ambient light sensor (lux), making it a versatile two-in-one module for proximity and light measurement.

Using an invisible laser and matching sensor, the VL6180X precisely times how long light takes to bounce back — delivering accurate readings without the linearity issues of IR reflectance sensors or the wide cone of ultrasonic sensors. The breakout includes a 2.8V regulator and level shifting for 3–5V compatibility.

Key Features

• Close-Range ToF Sensing – ~5 to 100 mm range (up to 150–200 mm in ideal conditions)
• Built-in Lux Sensor – Ambient light measurement included alongside distance sensing
• Narrow Sensing Cone – Focused invisible laser measures only the surface directly ahead
• I2C Interface – Simple two-wire communication; most processing handled on-chip
• 3–5V Compatible – On-board 2.8V regulator and level shifting
• Compact Breakout – Small PCB suitable for robotics and interactive projects

Compared To Other ToF Sensors

• vs VL53L0X – The VL53L0X covers ~50–1200 mm for longer-range needs but lacks the lux sensor
• vs VL53L4CD – The VL53L4CD covers ~1–1300 mm, combining close and medium range without a lux sensor

Ideal For

• Close-range proximity detection (gesture sensing, paper detection)
• Robotics obstacle detection at short distances
• Combined distance and ambient light sensing
• Interactive installations and touch-free interfaces
