Description
ALS-PD70-01C/TR7 Ambient Light Sensor Device, consisting of a photodiode in miniature SMD
package, which is molded in water clear with flat top. It is a good effective solution to the
power saving of display backlighting of mobile appliances, such as the mobile phones and PDAs.
Due to the high rejection ration of infrared radiation, the spectral response of the ambient light
sensor is close to that of human eyes.
Applications
• Detection of ambient light for controlling the backlighting of TFT LCD display
• Automatic residential and commercial lighting management
• Automatic contrast enhancement for electronic signboard
• Ambient light monitoring device for daylight and artificial light
