Gravity Arduino Analog Turbidity Sensor In Pakistan

The

gravity

arduino

turbidity

sensor

detects

water

quality

by

measuring

the

levels

of

turbidity.

It

uses

light

to

detect

suspended

particles

in

water

by

measuring

the

light

transmittance

and

scattering

rate,

which

changes

with

the

amount

of

total

suspended

solids

(TSS)

in

water.

As

the

TTS

increases,

the

liquid

turbidity

level

increases.

Turbidity

sensors

are

used

to

measure

water

quality

in

rivers

and

streams,

wastewater

and

effluent

measurements,

control

instrumentation

for

settling

ponds,

sediment

transport

research

and

laboratory

measurements.

This

liquid

sensor

provides

analog

and

digital

signal

output

modes.

The

threshold

is

adjustable

when

in

digital

signal

mode.

You

can

select

the

mode

according

to

your

MCU.
