STMicroelectronics (STMicroelectronics, ST) in order to further strengthen its flying distance sensor (ToF) market status, introduced the second generation FlightSense technology, and is used to the new VL53L0X laser ranging sensor.
VL53L0X ToF ranging up to two meters length, accuracy within + / - 3% range. Measurement speed is faster than the previous generation products, distance measurement time is less than 30 milliseconds (ms); Work efficiency is higher, the normal mode power consumption is only 20 milliwatts (mW), standby power consumption only 5 micro ampere (mu). In 2.4 mmx4.4 mmx1mm encapsulate, is a minimum size among the similar products on the market.
Is different from the traditional near infrared sensors (infrared proximity sensors), VL53L0X provide accurate to mm measurement, and the color of the target object and reflectivity will not affect the range measurement results. Rapid response of FlightSense technology, laser assisted by smart phone companies use autofocus lens reputation in the industry, and to distinguish targets near or far away from the mobile. Because of the sensor inside micro controller distance calculation, and through the I2C bus interface and output data, so can the demand of the main controller of the system to a minimum.
Built-in transmitter emitting laser wavelength of 940 nm, to don't harm the eyes of the visible light, there will be no similar other near infrared sensor made of red light and scattered attention problem, the other to external light source of disturbance rejection. The sensor of digital architecture and function of automatic light compensation, in the ambient light still has high performance in the scene.
VL53L0X sensing ability can be widely used in a variety of functions, including the innovation of the gesture sensor or close to detect the user interface; Home appliance such as sweeping robot detection, cliff detection, the wall of the collision detection; Sanitary ware products, such as: faucet, to the dispenser, hand dryer and syringe; Other applications include laptop users state detection or power switch monitor, unmanned aerial vehicles and the Internet of things (IoT) products.
In order to make more fast and convenient, in the process of integration VL53L0X products provide application programming interface (API) software, the complete technical documents and source code. Developers can use X-ray NUCLEO - 53 l0a1 expansion board, connecting the STM32 NUCLEO series microcontroller development board, easily evaluate VL53L0X product performance.
