Turbidity Sensor COM41

Fr24,800 Fr24,000

The  turbidity sensor detects water quality by measuring level of turbidity. It is able 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.

Description

The turbidity sensor detects water quality by measuring level of turbidity. It is able 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.

This turbidity sensor have both analog and digital signal output modes. You can select the mode according to the MCU as threshold is adjustable in digital signal mode.

Turbidity sensors can be used in measurement of water quality in rivers and streams, wastewater and effluent measurements, sediment transport research and laboratory measurements.

Getting started with Turbidity Sensor

This time we will discuss about a tutorial on how to access the Turbidity Sensor or Arduino water turbidity sensor.I converted the voltage to NTU .The working principle of this turbidity sensor is the same as the proximity sensor because there is a  photodiode LED as a transmitter and a photo diode ( receiver ).And this sensor utilizes the light emitted on the LED which then reflects the results of the light that will be read by the sensor.

So the higher the level of turbidity of the water that will be detected, the level of light reflection received will be less, and vice versa.This Turbidity sensor provides analog and digital signal output modes.

Step1: Hardware required

Step2: Connecting the Hardware

Turbidity Sensor                             Arduino Uno

A                                                                 A0

G                                                                 GND

V                                                                  5V

 

Step3: Upload the sample sketch

#define SENSOR A0

float voltage,turbidity;

void setup()
{
Serial.begin(9600);
pinMode(SENSOR,INPUT);
}

void loop()
{
voltage=0.004888*analogRead(SENSOR); //in V
turbidity=-1120.4*voltage*voltage+5742.3*voltage-4352.9; //in NTU
if((voltage>=2.5)&(turbidity>=0))
{
Serial.println(“Voltage=”+String(voltage)+” V Turbidity=”+String(turbidity)+” NTU”);
delay(500);
}
}

Step5: Testing the circuit

when the sensor is  in clear water.

open your serial monitor by clicking on the icon in the right top corner(like search icon) see the picture below something like that

If the voltage reading is below 2.5 V, the NTU is set to 3000 which would be the maximum NTU value of the project.

when the sensor is not in clear water.

open your serial monitor by clicking on the icon in the right top corner(like search icon) see the picture below something like that
