Pressure Monitoring with Arduino

Introduction: Pressure monitoring is an essential aspect of many engineering applications, including industrial automation, robotics, and environmental sensing. In this article, we will explore the importance and utility of pressure monitoring and provide a detailed project example using Arduino. We will also include a list of components required for the project and provide example codes with detailed explanations.

Project: Our project aims to create a pressure monitoring system using Arduino. The objectives of this project are to measure and display pressure values in real-time and provide an alert when the pressure exceeds a certain threshold. This system can be utilized in various applications such as monitoring air pressure in pneumatic systems, water pressure in pipelines, or even blood pressure in medical devices.

Components: To build this project, you will need the following components:

1. Arduino Uno (1x) - [Link to purchase: example.com/arduino-uno]
2. Pressure Sensor (1x) - [Link to purchase: example.com/pressure-sensor]
3. LCD Display (1x) - [Link to purchase: example.com/lcd-display]
4. Breadboard (1x) - [Link to purchase: example.com/breadboard]
5. Jumper Wires (Male to Male) - [Link to purchase: example.com/jumper-wires]

Examples: Example 1: Pressure Measurement and Display

#include <LiquidCrystal.h>

const int pressurePin = A0;
const int lcdPinRS = 12;
const int lcdPinEN = 11;
const int lcdPinD4 = 5;
const int lcdPinD5 = 4;
const int lcdPinD6 = 3;
const int lcdPinD7 = 2;

LiquidCrystal lcd(lcdPinRS, lcdPinEN, lcdPinD4, lcdPinD5, lcdPinD6, lcdPinD7);

void setup() {
  lcd.begin(16, 2);
  lcd.print("Pressure Monitor");
}

void loop() {
  int pressureValue = analogRead(pressurePin);
  float pressurePsi = pressureValue * 0.0048828125;  // Convert ADC value to PSI

  lcd.setCursor(0, 1);
  lcd.print("Pressure: ");
  lcd.print(pressurePsi);
  lcd.print(" PSI");

  delay(1000);
}

Example 2: Pressure Threshold Alert

#include <LiquidCrystal.h>

const int pressurePin = A0;
const int lcdPinRS = 12;
const int lcdPinEN = 11;
const int lcdPinD4 = 5;
const int lcdPinD5 = 4;
const int lcdPinD6 = 3;
const int lcdPinD7 = 2;
const int threshold = 50;  // Threshold pressure value in PSI

LiquidCrystal lcd(lcdPinRS, lcdPinEN, lcdPinD4, lcdPinD5, lcdPinD6, lcdPinD7);

void setup() {
  lcd.begin(16, 2);
  lcd.print("Pressure Monitor");
}

void loop() {
  int pressureValue = analogRead(pressurePin);
  float pressurePsi = pressureValue * 0.0048828125;  // Convert ADC value to PSI

  lcd.setCursor(0, 1);
  lcd.print("Pressure: ");
  lcd.print(pressurePsi);
  lcd.print(" PSI");

  if (pressurePsi > threshold) {
    lcd.setCursor(0, 0);
    lcd.print("High Pressure Alert");
  }

  delay(1000);
}

Conclusion: Pressure monitoring is a crucial aspect of many engineering applications, and Arduino provides a versatile platform for implementing such systems. In this article, we explored the importance and utility of pressure monitoring and provided a project example with detailed explanations and code. By utilizing Arduino and the listed components, you can easily create your own pressure monitoring system for various applications.
