Across multiple electronic applications, the world's leading semiconductor supplier STMicroelectronics (STMicroelectronics, referred to as ST) introduced a new high-precision optical distance measurement (range-finding) module. Based on FlightSenseTM Time-of-Flight technology, the new product provides designers with superior ranging capabilities.
FlightSenseTM technology provides accurate distance data by measuring the time it takes for light to be reflected back by the target object. Traditional sensors can only report reflected signal strength and cannot provide accurate distances. Compared to traditional infrared ranging sensors, ST 's FlightSenseTM technology has unique advantages, including measuring distances farther (ranging is not directly related to the reflectivity of the target object), higher frame rate, and more power consumption. low.
ST 's VL6180X module integrates the FlightSenseTM proximity sensor and ambient-light sensor (ALS) to provide basic gesture recognition, simplifying user interface design while improving product performance. The new products support a number of innovative applications in the market, including smartphones, tablets, game consoles, while improving the performance of consumer electronics and industrial products.
FlightSenseTM technology is adopted by global electronics giant LG due to the laser autofocus feature of its G3 smartphone.
The VL6180X module is housed in a compact optical package of 4.8mm x 2.8mm x 1.0mm LGA12, which accurately measures target objects 100mm or more depending on the working environment. The module is equipped with an I2C interface and two programmable GPIO pins. The main controller controls the optical module through the I2C interface to read the data of the ranging or ambient light intensity; and the GPIO pin can be configured to perform the threshold application.
ST's new VL6180X Explorer evaluation kit allows designers to easily exploit the full potential of this proximity sensor module, allowing customers to quickly learn to use FlightSenseTM technology and support application development on real-world devices. The tool includes a pluggable USB interface, STM32Nucleo development board and VL6180X sensor expansion board. The VL6180X sensor expansion board integrates sensors, LED 4-digit display and ranging and ambient light sensing control switches. The display shows the target distance or ambient light intensity.
The VL6180X sensor is currently in volume production; the VL6180X Explorer Evaluation Kit is available today.
