Description
The ALS-PT204-6C/L177 is an ambient light sensor; It consists of a phototransistor in 3mm lamp.
EVERLIGHT ALS series products are good effective solution to the power saving of display backlighting
of mobile appliances, such as the mobile phones, NB and PDAs. Due to the high rejection ratio of
infrared radiation, the spectral response of the ambient light sensor is close to human eyes.
Applications
‧Detection of ambient light to control display backlighting
Mobile devices – mobile phones, PDAs
Computing device – TFT LCD monitor for Notebook computer
Consumer device – TFT LCD TV, video camera, digital camera, toys
‧Automatic residential and commercial management
‧Automatic contrast enhancement for electronic signboard
‧Ambient light monitoring device for daylight and artificial light
