STMicroelectronics VL6180X gesture and ALS module
The VL6180X combines ranging, ambient light sensing and gesture recognition capabilities in a single, ready-to-use reflowable module
The VL6180X combines ranging, ambient light sensing and gesture recognition capabilities in a single, ready-to-use reflowable module.
The VL6180X is the latest product based on ST’s patented FlightSenseTM 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.
