Turbidity and
Temperature
Sensor
The 165D6042P003 module measures the turbidity
(amount of suspended particles) of the wash
water in washing machines and dishwashers.
An optical sensor for washing machines is a
measuring product for a turbid water density or
an extraneous matter concentration using the
refraction of wavelength between photo transistor
and diode. By using an optical transistor and
optical diodes, an optical washing machine sensor
measures the amount of light coming from the
source of the light to the light receiver, in order to
calculate water turbidity.

Theory of Operation
The sensor operates on the principle that when light is
passed through a sample of water, the amount of light
transmitted through the sample is dependent on the
amount of soil in the water. As the soil level increases,
the amount of transmitted light decreases. The turbidity
sensor measures the amount of transmitted light
to determine the turbidity of the wash water. These
turbidity measurements are supplied to the dishwasher
controller, which makes decisions on how long to wash
in all the cycles. These decisions are made based on
a comparison between clean water measurements
(taken at the beginning of the wash cycle) and the wash
water turbidity measurement taken at the end of each
wash cycle. By measuring the turbidity of the wash
water, the dishwasher can conserve energy on lightly
soiled loads by only washing as long as necessary. This
will result in energy savings for the consumer.
