Convenient
Simple
Energy-saving
The proximity sensor with microcomputer that can shut off the screen
when human presence is detected, and the backlight brightness
control function provided by the ambient light sensor, contribute to
energy saving.

What is an optical proximity sensor?
Optical sensors detect the amount of reflected
(infrared) light
⇒ The detected object’s color (reflectivity) has some
influence on detectability, but if the object’s surface
material is uniform (for example, human skin), the amount
of reflected infrared light does not change much.
Proximity sensor:
A sensor that can sense physical proximity without
making physical contact with the detection target.
This sensor uses reflected light (infrared light) for detection.

Tech Today Development Information
The proximity sensor with integrated the ambient light sensor boosts user convenience thanks to the
screen shut-off when human presence is detected (provided by the proximity sensor), and backlight
brightness control (provided by the ambient sensor).
GP2AP002A00F is the industry’s smallest proximity
sensor.*1 *2
Through integration of the ambient light sensor (used
for detecting ambient brightness) and the proximity
sensor, the GP2AP002A00F takes up 8% less
mounting area than the area required for separate
mounting.
*1 As of November 25, 2008. Survey by SHARP.
*2 A sensor that can sense physical proximity without making
physical contact with the detection target. SHARP’s sensor uses
reflected light (infrared light) for detection.
Application Examples
When talking on the phone, the user’s
face may come in contact with the
touch panel and cause false operations
(unintended operations) to be executed
The LCD monitor is
sometimes too bright,
making it hard to use
the camera’s viewfinder
