Abstract :
Water is an essential material that is very instrumental in life and for human life.
Of course because about 80% of the human body consists of liquid, but also because in
the water there is a mineral element needed for human physical development, therefore it
is necessary to take action to see the level of clarity of water used in everyday life. Turbid
water is water that is not clean and healthy what else if it is used for ablution, therefore
the level of water clarity must be measured using turbidity sensor with Arduino Unobased
microcontroller
so
that
it
can
find
out
whether
the
water
is
suitable
for
use.
Then
the
sensor voltage in the form of analog data can be processed into digital data using
ADC (Analog to Digital Converter) and can be displayed on the LCD, so that it can detect
whether the water is clean or not clean (cloudy).
Arduino Uno functions as a control system of this device, the turbidity sensor is
used to detect the level of water clarity and selenoid valve is used to live and turn off the
water channel. This water level clarity detection system operates when the water in the
tank of the ablution tap is cloudy, the sensor will detect it so that the selenoid will be
closed and the water will no longer flow, so the buzzer will sound as well as the LED will
light up.
