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-9005
The APDS-9005 is a low cost analog-output ambient light
photo sensor whose spectral response closely emulates
the human eyes. APDS-9005 consists of a photo sensor
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-9005 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
dependant proportionally on the photo current which
generated 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.
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
frequency 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.
