Description
Ambient Photoresistor Light Sensors, made of chip, is sensitive to
ambient light. Its photopic response is close to human eye. RoHS
Compliant, it can be used as perfect replacement of Cds photocell.
It is a low cost analog-output ambient light photo sensor in
miniature chip LED lead-free surface mount package. It consists of
a photo sensor, whose spectral response is close to the CIE
standard photopic observer, as show in figure 2. EKPSMD3528 is ideal for applications in which the measurement of ambient light
is used to control display backlighting. Mobile appliances such as
the mobile phones and PDAs that draw heavy current from display
backlighting will benefit from incorporating these photo sensor
products in their designs by reducing power consumption
significantly.
