Description
The VL6180X is the latest product based on ST’s
patented FlightSense^™ technology. This is a
ground-breaking technology allowing absolute
distance to be measured independent of target
reflectance. Instead of estimating the distance by
measuring the amount of light reflected back from
the object (which is significantly influenced by
color and surface), the VL6180X precisely
measures the time the light takes to travel to the
nearest object and reflect back to the sensor
(Time-of-Flight).
Combining an IR emitter, a range sensor and an
ambient light sensor in a three-in-one ready-to-
use reflowable package, the VL6180X is easy to
integrate and saves the end-product maker long
and costly optical and mechanical design
optimizations.
The module is designed for ultra low power
operation. Ranging and ALS measurements can
be automatically performed at user defined
intervals. Multiple threshold and interrupt
schemes are supported to minimize host
operations.
Host control and result reading is performed using
an I²C interface. Optional additional functions,
such as measurement ready and threshold
interrupts, are provided by two programmable
GPIO pins.
Applications
• Smartphones/portable touchscreen devices
• Tablet/laptop/gaming devices
• Domestic appliances/industrial devices
