Electronic applications across multiple fields, the world’s leading semiconductor supplier STMicroelectronics (STMicroelectronics, referred to as ST) introduced a new high-precision optical distance (range-finding) module. The new product is based on FlightSenseTM flight time measurement technology (Time-of-Flight technology), providing designers with superior ranging capabilities.

FlightSenseTM technology is through measurement of the light reflected by the target object by using the time to provide accurate distance data. The conventional sensors can only report reflected signal strength, can not provide an accurate distance. Compared with conventional infrared distance sensors, STMicroelectronics FlightSenseTM technology has unique advantages, including measuring the distance farther (reflectivity ranging with the target object is not directly related), frame rate (frame rate) higher power and more low.
STMicroelectronics VL6180X module integrates FlightSenseTM proximity sensors (proximity sensor) and the ambient light sensor (ALS, ambient-light sensor), provides the basic gesture recognition, simplified user interface design, while improving product performance. The new product supports a number of innovative applications on the market, including smart phones, tablet PCs, game controller, while providing increased performance consumer electronics and industrial products.
FlightSenseTM technical access to global electronics giant LG use, because of its smart phone G3 laser autofocus.
VL6180X module uses 4.8mm x 2.8mm x 1.0mm compact optical package LGA12 can be based on the work environment, the precise determination of 100mm or more distant target object. The module is equipped with I2C interface and two programmable GPIO pins. Master controller via the I2C interface to control the optical module, read distance or ambient light intensity data; while GPIO pins can be configured to achieve the implementation of the threshold (threshold) applications.
STMicroelectronics new VL6180X explorers evaluation kit allows designers to easily close the full potential of this sensor module not only allow customers to quickly learn how to use FlightSenseTM technology, but also on the actual device support application development. The tool contains pluggable USB interface, STM32Nucleo development board and VL6180X sensor expansion board. And VL6180X sensor expansion board integrates sensors, LED 4 digit display and ranging and ambient light sensing function control switch. The display shows the target distance or ambient light intensity.
