Arduino UNO Based Gas Leak Detector with GSM Notification and Servo Valve Control

This circuit is designed as a gas leakage detection system with SMS alert capabilities. It uses an Arduino UNO to monitor MQ-6 and MQ-7 gas sensors for LPG and CO levels, respectively, and activates a servo-controlled valve, buzzer, and exhaust fan if gas concentrations exceed preset thresholds. Additionally, the system uses a SIM900A GSM module to send SMS alerts in case of gas detection, and it is powered by a series of 18650 Li-ion batteries managed by a protection board.

ESP32-Based Gas Detection System with Wi-Fi Notification

This circuit is a gas detection system using an ESP32 microcontroller connected to three gas sensors (MQ2, MQ-4, and MQ-7). The ESP32 reads both digital and analog signals from the sensors to monitor gas levels and sends notifications via Blynk if any gas concentration exceeds a predefined threshold.

Battery-Powered Gas Sensor with Buzzer Alert using MQ-2 and LM7805

This circuit is a gas detection system powered by a 9V battery, which uses an MQ-2 gas sensor to detect gas levels. The sensor's analog output controls an NPN transistor, which in turn activates a buzzer to provide an audible alert when gas is detected. The LM7805 voltage regulator ensures a stable 5V supply to the sensor and other components.

Arduino-Based Gas Leakage Detector with MQ-2 Sensor and SIM900A GSM Module

This circuit is a gas leakage detection system that uses an MQ-2 gas sensor to monitor gas levels. If the gas level exceeds a predefined threshold, the Arduino UNO triggers a buzzer, activates a cooling fan, opens a valve using a servo motor, and sends an SMS alert and makes a call via the SIM900A GSM module.

Usage Instructions

How to Use the Component in a Circuit

1. Power Supply: Connect the VCC pin to a 3.3V or 5V power supply and the GND pin to the ground.
2. Analog Output: Connect the AOUT pin to an analog input pin on your microcontroller to read the ammonia concentration.
3. Digital Output: Connect the DOUT pin to a digital input pin on your microcontroller to detect if the ammonia concentration exceeds a predefined threshold.

Important Considerations and Best Practices

• Calibration: Allow the sensor to warm up for at least 24 hours before taking accurate measurements.
• Placement: Place the sensor in an area with good airflow to ensure accurate readings.
• Power Supply: Ensure a stable power supply to avoid fluctuations in sensor readings.
• Humidity and Temperature: Operate the sensor within the specified humidity and temperature ranges to maintain accuracy.

Example Code for Arduino UNO

// Include necessary libraries
const int analogPin = A0; // Analog input pin connected to AOUT
const int digitalPin = 2; // Digital input pin connected to DOUT

void setup() {
  Serial.begin(9600); // Initialize serial communication at 9600 baud
  pinMode(digitalPin, INPUT); // Set digital pin as input
}

void loop() {
  int analogValue = analogRead(analogPin); // Read the analog value
  int digitalValue = digitalRead(digitalPin); // Read the digital value

  // Convert the analog value to a voltage
  float voltage = analogValue * (5.0 / 1023.0);

  // Print the analog value and voltage to the serial monitor
  Serial.print("Analog Value: ");
  Serial.print(analogValue);
  Serial.print(" - Voltage: ");
  Serial.print(voltage);
  Serial.println("V");

  // Check if the digital output is high
  if (digitalValue == HIGH) {
    Serial.println("Ammonia concentration exceeds threshold!");
  } else {
    Serial.println("Ammonia concentration is below threshold.");
  }

  delay(1000); // Wait for 1 second before the next reading
}

Troubleshooting and FAQs

Common Issues Users Might Face

1. Inaccurate Readings: Ensure the sensor has been calibrated and has had sufficient warm-up time.
2. No Output Signal: Check the power supply connections and ensure the sensor is receiving the correct voltage.
