Features VL6180X high-precision range-finding module VL6180 proximity sensor ambient light sensor gesture recognition development board IR emitter: 850nm 12Caddress: 0x29 (7-bit) Ambientlight sensor: 0.038 to 50klux (2) 16-bit output (3) ST launched a new rangefinding module with high accuracy. New product based on FlightSense "Time-of-Flightechnology" , Can bring more excellent distance measurement function for designers. "FlightSense" technology provides accurate distance data by measuring the time that light is reflected back from a target object. Traditional sensors can only report the strength of the reflected signal and cannot provide an accurate distance. Compared with traditional infrared sensors,STMicroelectronics' FlightSense " The technology has more unique advantages, including longer measurement distance (the distance measurement has no direct relationship with the reflectivity of the target object), high framerate, and low power consumption. STMicroelectronics' VL6180X The module integrates FlightSense "proximity sensor" and ambient-lightsensor (ALS) to provide basic gesture recognition functions, simplify user interface design and improve product performance. New products can support the market A number of innovative applications, including smartphones, tablets, and game control systems, while improving the performance of consumer electronics and industrial products. "F1ightSense" technology is adopted by global electronics giant LG for its laser autofocus function on its G3 smartphone. The VL6180X module uses a compact optical package of 4.8mm × 2.8mmx; 1.0mm LGA12, which can accurately measure 100mm or more target objects according to the working environment. The module is equipped with an I2C interface and two programmable GPI0 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 pins of the GPIO can be configured to implement threshold applications. The new VL6180X Explorer evaluation kit from STMicroelectronics enables designers to easily realize the full potential of this proximity sensor, which not only enables customers to quickly get started with FlightSense "technology systems, but also supports the application development of actual devices. The kit Includes detachable USB connector, STM32Nucleod development board and VL6180X sensor expansion board. The VL6180X sensor expansion board integrates the sensor, 4-bit LED display and switchable functions of controllable ranging and ambient light sensing switch. The display will show and Data on the distance of the target or the intensity of the ambient light. |
