The Water Turbidity Sensor with Analog Output Module is designed for measuring the turbidity of water, which is an indicator of water quality. This sensor is commonly used in water treatment plants, environmental monitoring, and scientific research to assess water clarity and detect the presence of suspended particles.

Key Features

• Analog Output: Provides an analog voltage signal proportional to the turbidity level of the water.
• High Sensitivity: Detects even low levels of turbidity with accuracy.
• Durable Construction: Built to withstand harsh environmental conditions.
• Easy Integration: Simple to connect with microcontrollers like Arduino for real-time monitoring and data logging.

Specifications

• Measurement Range: Typically 0 to 1000 NTU (Nephelometric Turbidity Units)
• Output Signal: Analog voltage (usually 0 to 3V or 0 to 5V depending on the module)
• Power Supply: 5V DC (can be powered directly from Arduino or other microcontrollers)
• Response Time: Fast response for real-time monitoring
• Accuracy: ±5% of the full scale
• Operating Temperature Range: 0°C to 50°C
• Dimensions: Compact module size for easy integration (dimensions may vary based on manufacturer)

Applications

• Water quality monitoring in treatment facilities.
• Environmental research and monitoring.
• Educational projects related to water science.
• Industrial applications where water clarity is a critical parameter.

How to interface with Arduino?

To interface a Water Turbidity Sensor with Analog Output Module with an Arduino UNO, follow these steps:

1. Wiring Connections

The Water Turbidity Sensor typically has the following pins:

• VCC: Power supply (usually 5V)
• GND: Ground
• ANALOG OUT: Analog signal output

Wiring:

• VCC to 5V on Arduino
• GND to GND on Arduino
• ANALOG OUT to Analog Pin A0 on Arduino

2. Code Example

Here’s a simple code example to read the turbidity values from the sensor and print them to the Serial Monitor:

// Pin connected to the sensor's analog output
const int sensorPin = A0;

void setup() {
  Serial.begin(9600); // Initialize serial communication
}

void loop() {
  int sensorValue = analogRead(sensorPin); // Read the analog value from the sensor
  Serial.print("Turbidity Value: ");
  Serial.println(sensorValue); // Print the sensor value to the Serial Monitor
  delay(1000); // Wait for 1 second before reading again
}

3. Important Notes

• Calibration: The sensor may need calibration to provide accurate turbidity readings. Typically, this involves comparing readings with known turbidity standards.
• Power Supply: Ensure that the sensor is powered with 5V from the Arduino.
• Reading Range: The analog output from the sensor will range from 0 to 1023, where 0 represents the lowest turbidity and 1023 represents the highest turbidity detected.
