IoT Industry Protection System Using Arduino

This guide will help you create an IoT-based industry protection system using Arduino. The system will monitor various environmental parameters and provide real-time alerts for potential security breaches or unsafe conditions.

Components Required

• Arduino board (e.g., Arduino Uno)
• Ultrasonic sensors (for distance measurement)
• Gas sensors (e.g., MQ series for detecting gases like methane, carbon monoxide)
• Temperature and humidity sensors (e.g., DHT11 or DHT22)
• Relay module (for triggering alarms or actions)
• Connecting wires and breadboard
• Power supply (for Arduino and sensors)
• Cloud service account (e.g., ThingSpeak, Blynk, or AWS IoT)
• Buzzer or alarm (optional, for local alerts)

Setting Up the Hardware

Follow these steps to set up the hardware:

1. Connect the Ultrasonic Sensors

   Attach the ultrasonic sensors to measure distance and detect intrusions. Connect the sensors to the Arduino using the appropriate pins.

2. Connect the Gas Sensors

   Wire the gas sensors to the Arduino to detect the presence of hazardous gases. Ensure proper calibration and connection.

3. Integrate Temperature and Humidity Sensors

   Connect the temperature and humidity sensors to the Arduino to monitor environmental conditions.

4. Set Up the Relay Module

   Wire the relay module to the Arduino. The relay can be used to trigger alarms or other safety measures if unsafe conditions are detected.

5. Power the System

   Ensure all components are properly powered. Use a suitable power supply for the Arduino and sensors.

Programming the Arduino

Write the code to read data from the sensors and send alerts to the cloud. Below is a basic outline of the code using Arduino IDE:

                #include <Wire.h>
                #include <Adafruit_Sensor.h>
                #include <DHT.h>

                // Sensor pins
                const int ultrasonicTriggerPin = 9;
                const int ultrasonicEchoPin = 10;
                const int gasSensorPin = A0;
                const int relayPin = 8;

                // DHT sensor
                #define DHTPIN 2
                #define DHTTYPE DHT22
                DHT dht(DHTPIN, DHTTYPE);

                void setup() {
                    Serial.begin(9600);
                    pinMode(ultrasonicTriggerPin, OUTPUT);
                    pinMode(ultrasonicEchoPin, INPUT);
                    pinMode(gasSensorPin, INPUT);
                    pinMode(relayPin, OUTPUT);
                    dht.begin();
                }

                void loop() {
                    // Read ultrasonic sensor
                    digitalWrite(ultrasonicTriggerPin, LOW);
                    delayMicroseconds(2);
                    digitalWrite(ultrasonicTriggerPin, HIGH);
                    delayMicroseconds(10);
                    digitalWrite(ultrasonicTriggerPin, LOW);
                    long duration = pulseIn(ultrasonicEchoPin, HIGH);
                    float distance = duration * 0.0344 / 2;

                    // Read gas sensor
                    int gasLevel = analogRead(gasSensorPin);

                    // Read temperature and humidity
                    float temperature = dht.readTemperature();
                    float humidity = dht.readHumidity();

                    // Check conditions and trigger relay if necessary
                    if (distance < 10 || gasLevel > 500 || temperature > 30) {
                        digitalWrite(relayPin, HIGH);
                    } else {
                        digitalWrite(relayPin, LOW);
                    }

                    // Print values
                    Serial.print("Distance: ");
                    Serial.print(distance);
                    Serial.print(" cm\t");
                    Serial.print("Gas Level: ");
                    Serial.print(gasLevel);
                    Serial.print("\tTemperature: ");
                    Serial.print(temperature);
                    Serial.print(" C\t");
                    Serial.print("Humidity: ");
                    Serial.print(humidity);
                    Serial.println(" %");

                    // Send data to cloud (pseudo-code, replace with actual API call)
                    // sendDataToCloud(distance, gasLevel, temperature, humidity);

                    delay(1000); // Delay between readings
                }
            

This code reads data from the ultrasonic, gas, and temperature/humidity sensors, and triggers a relay if unsafe conditions are detected. Replace the pseudo-code with actual API calls to send data to your cloud service.

Setting Up Cloud Integration

To visualize and analyze the data, integrate the system with a cloud service. Configure your cloud service to receive data from the Arduino and set up dashboards or alerts based on the collected data for distance, gas levels, temperature, and humidity.

Testing and Calibration

Test the system by simulating various conditions to ensure the sensors and relays function correctly. Calibrate the sensors as needed and verify that data is accurately sent to the cloud.
