GP2D12J0000F provides an analog output proportional to the distance to the detection object,
whereas the output of the GP2D15J0000F is logical High or Low according to whether the detec-
tion object is further or closer than the specified distance (24 cm).
The distance characteristics of the output of the GP2D12/15J0000F are almost completely unaf-

dust sensor
GP2Y1010AU0F due to tobacco smoke and house dust
The GP2Y1010AU0F dust sensor electro-optical characteristics are shown in table 12-2.
The rate of change in output voltage relative to a change in the dust concentration of the
air is indicated as the detection sensitivity. An example of the dust concentration characteristics
of GP2Y1010AU0F is shown in Fig. 12-12.
Using the output voltage of the GP2Y1010AU0F, it is possible to identify whether the detected
particles in the air are tobacco smoke or house dust. Fig. 12-13 shows the differences in the
GP2Y1010AU0F output when tobacco smoke and house dust are detected.
When tobacco smoke first spreads through the air and reaches the detection area of the
GP2Y1010AU0F, the sensor output voltage (pulse output voltage) increases.
Tobacco smoke is continuously present in the sensor detection area. and the amplitude of

With the GP2Y1010AU0F there is a variation between individual products in the output
with no dust and the detection sensitivity of the GP2Y1010AU0F will drop, and the detected
