GP2U06
High Sensitivity Dust Sensor
Compact and Thin Type Dust Sensor for Detecting Particles
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.
(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/m
3
)
(4) Operating voltage : 5V
(5) Low dissipation current (Icc : MAX. 15mA)

As of May 1997
*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
0.1mg/m
3
from the initial value.
*2 Input conditions to LED terminal (pulse operation condition) is shown in the right figure.
