Ambient Light Sensors

An ambient light sensor is a major component in smart devices such as smartphones, notebooks, laptops, LCDs, TVs and automotive displays. The ambient light can be sensed by using a photo detector to find the amount of ambient light present. And it can also dim the device screen to match it. This could prevent the screen from being too bright. This is because the audience pupil has to adapt to vision in the darkroom. And similarly, too dim is also problematic when the device is used outdoors during the daytime. Dimming the screen on these smart devices, such as mobile laptops, also lengthens the battery's lifetime. 

The Lux is the standard international unit for the luminance of ambient light. The standard performance of an ambient light sensor is less than 50 lux in dim light to more than 10,000 lux at noon. They are automated to make changes in the display brightness on these smart devices by sensing changes in the surrounding, like lights on and off.

Unique Features and Benefits

  • Very well operation in a variety of sources 
  • Automatic adapt or adjustment based on surrounding analysis.
  • Light sensitivity and reacts curve configured with the human eye in mind
  • Mostly reliable over specific temperature ranges.
  • Accurate Lux, distance measurement information, and correlated color temperature.
  • Easy configuration in all in one module.
  • Power consumption is very low
  • Competitive system cost

Ambient Sensor Light Applications

  • Touchable panels
  • Smart devices and intelligent devices
  • Home appliances 
  • Laptops
  • Smartphones

Ambient Light Sensor Performance 

ST ambient light sensor provides an optimized suite and color filter with accurate responses that transforms ambient light into lux values with the best accuracy performance. 

Full-color sensors offer a compact optical sensing solution integrating the computation of the association color temperatures and the flickering frequencies extraction of the artificial light. The banding effect visible on the camera screen can be removed effectively.

Ambient light sensors integration with IR emitter and ST's patented Flight sense, the 3-in 1 combo sensors are convenient to combine and make use well of the end-product maker long and mechanical specification optimization.

Light dimension is fast and very precise; good to say thanks to the ADC and readout circuitry for every color channel, such as Red, Green, Blue, IR, clear and shiny. The VD6283TX uses hybrid color filters with accurate reactions accepting precise computation of the associated color temperatures and information that Lux provides for scene light correction and brightness management of display. Moreover, the VD6283TX can pull out flickering light frequencies from 100 Hz to kHz.

Ambient light sensors are available in the market with a complete documentation package, such as source code and software APIs. This is well suited with a range of processors and microcontrollers. X-NUCLEO expansion and breakout boards play a great role in making easy the integration of software development and the physical combination into users' devices. They are also compatible with other standards of light sensors available in the market, such as STM32 ODE environment and STM32CubeMX graphical user interface and initialization code generator.
