Sharp GP2U06 Datasheet

GP2U06 High Sensitivity Dust Sensor

Compact and Thin Type Dust Sensor for Detecting Particles

General Description

Sharp's GP2U06 is dust sensor which integrated optical
sensor portion and signal amplifier portion.
It is suitable for indoor air purifier sensor because of
compact, thin, low dissipation current type.

Features

(1) Compact, thin type (58 x 38 x 25mm)
(2) High sensitivity

(Dust detecting sensitivity : TYP.0.5V/(0.1mg/m

3

)

(3) Can detect dust even in low density area

(Minimum particle density : TYP. 0.02mg/m3)
(4) Operating voltage : 5V
(5) Low dissipation current (Icc : MAX. 15mA)

Applications

(1) Air purifiers
(2) Air conditioners

*1 • Dust density is measured by mildseven smoke density, using digital dust meter [P-5L2 made by
SHIBATA scientific instrumental industry].

• Detecting sensitivity is settled according to the change of output voltage when dust density change
