Description
The ALS-PDIC243-3C is an ambient light sensor, which incorporates a photodiode and a current
amplifier IC in DIP package. EVERLIGHT ALS series products are a 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
– Street light, CCD/CCTV
