What it is

The MQ-5 module is a semiconductor sensor designed to detect the presence of LPG and natural gas. It is an economical and easy-to-integrate device for home or industrial security projects.

Features

• LPG and Natural Gas Detection
• Arduino Compatible Module
• SKU: ARD00210
• Price: 7.14 €

What it is for

The MQ-5 sensor can be used to create home alarm systems that send notifications in case of LPG detection. It can be integrated into industrial security projects to monitor dangerous gas concentrations. Compatibility with Arduino and similar platforms makes it easy to use in automation and control projects.

Tutorial: How to Use MQ-5 Gas LPG Detection Module

The MQ-5 sensor is a useful device for detecting LPG and natural gas. Ideal for home or industrial security projects.

What you need

• Arduino Uno
• USB Cable
• Connect to Computer
• Arduino IDE Software

Steps

1. Connect the VCC, GND, AO pins of the MQ-5 sensor to the corresponding pins of the Arduino.
2. Install the Adafruit_ADS1015 library if it is not already present in your project.
3. Write and upload the Arduino sketch to read the analog value from the sensor.
4. Check the read values on the serial monitor of the Arduino IDE software.
5. Adjust the alarm levels according to the specifications of the MQ-5 sensor datasheet.
6. Test the system with GPL gas or similar, respecting safety precautions.
7. Implement a notification system (e.g., LED, sound) when a danger is detected.
8. Document your project and share it with the maker community.

Example code

/* Includi la libreria */
#include <Adafruit_ADS1015.h>

// Creazione dell'oggetto ADS1X15
Adafruit_ADS1015 ads = Adafruit_ADS1015();

void setup() {
  Serial.begin(9600);
}

void loop() {
  int val = ads.readADC_SingleEnded(0); // Leggi il valore dal sensore
  Serial.println(val); // Stampa il valore sul monitor seriale
}

Mini project

Create a home alarm system that sends an email notification when GPL gas is detected.

Common mistakes

• Do not correctly connect the sensor pins.
• Ignore safety precautions during testing.
• Do not verify the read values on the datasheet.
