An ambient light sensor is a component in smartphones, notebooks, other mobile devices, automotive displays and LCD TVs.It is a photodetector that is used to sense the amount of ambient light present, and appropriately dim the device's screen to match it. This avoids having the screen be too bright when the user's pupils are adapted for vision in a dark room, or too dim when the device is used ...
This specification defines a concrete sensor interface to monitor the ambient light level or illuminance of the device’s environment.

High Accuracy Ambient Light Sensor With I²C Interface. Datasheet. FEATURES
The OPT3001 is a sensor that measures the intensity of visible light. The spectral response of the sensor tightly matches the photopic response of the human eye and includes significant infrared rejection.
The Ambient Light Sensor (ALS) products from ams provide measurements of ambient light intensity which match the human eye’s response to light under a variety of lighting conditions.
Overview of TI's ambient light sensor portfolio; includes ambient light sensors (ALS), UV sensors, LED control sensors, and light proximity sensors for backlight control and spectral response measurement.
Abstract. The Permissions Standard defines common infrastructure for other specifications that need to interact with browser permissions. It also defines an API to allow web applications to query and request changes to the status of a given permission.
The ambient light sensor on the newer Unibody MacBook Pro (all models: 13″, 15″, 17″) is located directly next to the iSight camera at the top of the display. You can verify the location by holding your hand over the area to the left of the iSight camera and watch as your screen dims and the keyboard lights brighten.
Ultrasonic sensor (distance) The ultrasonic sensor measures distance to an object up to a maximum of 255cm (or 100 inches) away. It does this by sending out high frequency sound waves that bounce off any object in range, and measuring how long it takes the sound to return to the sensor.
