VL6180X
3-in-1time-of-flight module:
proximity sensor, ALS and gesture
d
VL6180X combines a light source, proximity sensor and ambient light
sensor (ALS) in a single integrated module
The VL6180X is the latest
product based on ST’s patented
FlightSense™ technology. The
VL6180X module uses the timeof-flight measurement principle
to implement a proximity sensor,
offering significant advantages
over conventional infra-red (IR)
technology. The module also
includes an ambient light sensor.
KEY BENEFITS
• Fully integrated module : IR emitter, Ranging sensor and ALS.
No need of external LEDs
• SPAD array based (single photon avalanche diode) : unique product on
market
• Absolute distance measurement
(in millimeters, register output)
• Accurate and low power (early
convergence mode or continuous mode)
• Independent of target reflectance : work
with dark colours, gloves, ...
TARGETED APPLICATIONS
• Mobile devices
Proximity detection
Ambiant light sensing
• 1D gesture control
• Domestic appliances
• Power on/off, volume +/• Liquid level monitoring or selection
• Collision avoidance for cleaning
robots (wall and cliff)
• Industrial
• Object detection and ranging
• Human-machine interface

SYSTEM ARCHITECTURE
The VL6180X contains an array of SPAD (Single Photon Avalanche Diode) detectors. The SPAD array forms part of an advanced system
architecture that can detect the arrival of individual photons and hence calculate the time taken for the photon to leave the module, hit the target
and then return back to the module. Actual distance measurement combined with signal amplitude allows simple but robust gesture recognition
to enable multiple use cases.
Furthermore the VL6180X’s ultra-low-power system architecture is perfectly suited to the demanding requirements of wireless and consumer
products.
MODULE DESIGN
All components to support the proximity sensor and ambient light sensor are embedded in the simple optical module. No mechanical gaskets or
additional lens systems are required to complete the industrial design.
The module can be mounted on the host PCB using a standard reflow profile or flex attached.
Its unique time-of-flight properties allow the module to be hidden behind a wide variety of cover-glass materials. This enables very innovative
product design with the possibility of removing the hole that normally forms part of the industrial design.
