Use of ambient light sensor in mobile

Sensors commonly used in handsets include accelerometer, gyroscope, proximity sensor, ambient light sensor , and barometer. The ALS approximates human eye response to light . These sensors work well in all . One very important application for. The concerns of power consumption and viewing comfort have led many of these devices to include ambient light sensors —in an effort to make the device aware of its surroundings.

In dim environments the display backlight can be dialed back to save battery power, and in bright environments the enhanced use of fonts and .

Analog ambient light sensors with built-in photodiode and current amplifier circuit , which controls the display luminosity depending on ambient brightness and so is ideal for mobile equipments requiring low-power consumption.

ON Semiconductor supplies ambient light sensors and proximity sensors with high sensitivity for mobile , consumer, and industrial applications. Content) for the purpose of enabling Licensee to use the Content and then . Interesting application of light sensor ! Using the ambient light sensor instead of the camera greatly benefits energy consumption, bandwidth usage and raises less privacy concerns. Their ultra low light sensitivity, low power consumption, ideal spectral response, and easy to use simple output algorithm make them best-in-class. Proximity sensor with integrated ambient light sensor.

Use of the proximity sensor to detect face. I2C bus communication interface and additional interrupt feature. The ambient light result is as digital value available. It features an interrupt function. Similarly to proximity sensor, the way mechanism is being used makes little difference for this privacy analysis.

This sensor is placed in the top. Somewhat unsurprisingly, light . Ambient Light Sensors use is simple. Broadcom ambient light sensors are used for display . IF YOU DO NOT WISH TO SO AGREE, DO NOT DOWNLOA COPY, INSTALL, OR USE THE CONTENT. Support sensors - accelerometer, ambient light , barometer, compass, gyroscope, magnetometer, pedometer, and proximity.

Higher reliability, Capacitive proximity sensing is immune to ambient light , whereas it has been observed that IR based sensing can have performance issues based on ambient light frequency. You can use data from light sensors to automatically adjust screen brightness and keyboard illumination. You can also create light-aware applications that adjust user interface elements for current lighting conditions.
