How to Use sensor_fluxo: Examples, Pinouts, and Specs

The Sensor Fluxo is a versatile electronic component designed to measure the flow rate of liquids or gases in a system. It is widely used in various applications, including industrial automation, water management systems, HVAC systems, and medical devices. By providing accurate flow rate measurements, the Sensor Fluxo helps in monitoring and controlling fluid dynamics, ensuring efficient and safe operation of systems.

1. Power Supply: Connect the VCC pin to a 5V DC power supply.
2. Ground Connection: Connect the GND pin to the ground of the circuit.
3. Signal Output: Connect the Signal pin to a digital input pin of a microcontroller (e.g., Arduino UNO).

+5V (Arduino) ----> VCC (Sensor Fluxo)
GND (Arduino) ----> GND (Sensor Fluxo)
Digital Pin 2 (Arduino) ----> Signal (Sensor Fluxo)

// Define the pin where the sensor is connected
const int sensorPin = 2;

// Variables to store pulse count and flow rate
volatile int pulseCount = 0;
float flowRate = 0.0;

void setup() {
  // Initialize serial communication
  Serial.begin(9600);
  
  // Set the sensor pin as input
  pinMode(sensorPin, INPUT);
  
  // Attach an interrupt to the sensor pin
  attachInterrupt(digitalPinToInterrupt(sensorPin), pulseCounter, RISING);
}

void loop() {
  // Calculate flow rate (L/min)
  flowRate = (pulseCount / 45.0); // 45 pulses per liter
  
  // Print the flow rate to the serial monitor
  Serial.print("Flow Rate: ");
  Serial.print(flowRate);
  Serial.println(" L/min");
  
  // Reset pulse count for the next measurement
  pulseCount = 0;
  
  // Wait for 1 second before the next measurement
  delay(1000);
}

// Interrupt service routine to count pulses
void pulseCounter() {
  pulseCount++;
}

• Power Supply: Ensure a stable 5V DC power supply to avoid inaccurate readings.
• Mounting: Install the sensor in a straight section of the pipe to minimize turbulence.
• Orientation: Follow the manufacturer's guidelines for the correct orientation of the sensor.
• Calibration: Periodically calibrate the sensor to maintain accuracy.

1. No Output Signal:

   • Check Connections: Ensure all connections are secure and correct.
   • Power Supply: Verify that the sensor is receiving the correct voltage.

2. Inaccurate Readings:

   • Calibration: Recalibrate the sensor.
   • Flow Disturbances: Ensure the sensor is installed in a straight section of the pipe.

3. Intermittent Signal:

   • Electrical Noise: Use shielded cables to reduce electrical noise.
   • Loose Connections: Check for any loose or corroded connections.

Q1: Can the Sensor Fluxo be used with liquids other than water? A1: Yes, the Sensor Fluxo can measure the flow rate of various liquids and gases, but ensure the material compatibility with the fluid.

Q2: How often should the sensor be calibrated? A2: Calibration frequency depends on the application and usage. For critical applications, calibrate the sensor every 6 months.

Q3: Can the sensor be used in high-pressure systems? A3: The Sensor Fluxo is designed for standard pressure systems. For high-pressure applications, consult the manufacturer for suitable models.

By following this documentation, users can effectively integrate and utilize the Sensor Fluxo in their projects, ensuring accurate and reliable flow rate measurements.
