2.1 Optical Window Material
The material of the window is recommended to be poly-
carbonate. The surface finish of the plastic should be
smooth, without any texture.
The recommended plastic material for use as a window is
available from Bayer AG and Bayer Antwerp N. V. (Europe),
Bayer Corp.(USA) and Bayer Polymers Co., Ltd. (Thailand),
as shown in Table 2.

Appendix C . General Application Guide for APDS-9008
The APDS-9008 is a low cost analog-output ambient light
photo sensor whose spectral response closely emulates
the human eyes. APDS-9008 consists of a photo sen-
sor that is able to produce a high gain photo current to
a sufficient level that can be converted to voltage with a
standard value of external resistor. APDS-9008 can easily
be integrated into systems that use ADC input which is
available for sampling of the external source, as shown in
figure C1 below.
The amount of converted voltage, Vout, is mainly depen-
dant proportionally on the photo current which generated

Source
by the brightness of the light shone on the photo sensor
and the load resistor used, RL. Increasing the brightness of
the light or/and the load resistor will increase the output
voltage.
Brightness is measured as “LUX” unit, which describes how
intense a light source that our eyes perceive. LUX meter is
the equipment for “LUX” measurement. Light sources with
the same LUX level appear at the same brightness to the
human eyes.
Figure C1. Configuration of APDS-9008
Selection of the load resistor RL will determine the amount
of current-to-voltage conversion in the circuit.
Light source e.g. fluorescent light consists of ac noise fre-
quency of about 100Hz. A capacitor of 10uF, which act as a
low-pass filter, is recommended to add in parallel with the
load resistor to reduce the ripples.
