MQ-6 Gas Sensor Module For Propane, Butane, And LPG Detector Module
MQ-6 Gas Sensor Module For Propane, Butane, And LPG Detector Module
The MQ-6 Gas Sensor Module is a highly sensitive and reliable gas detection module designed to detect propane, butane, and LPG (Liquefied Petroleum Gas) in the air. This module is widely used in various applications, including industrial, commercial, and residential settings, to detect and alert users of potential gas leaks.
The MQ-6 Gas Sensor Module utilizes a detection principle based on the catalytic combustion method, which involves the combustion of gases on a heated surface. When a gas molecule comes into contact with the sensor, it reacts with the catalyst, resulting in a change in the electrical resistance of the sensor. This change is then measured and amplified by the onboard circuitry to produce a corresponding analog output signal.
| ### Sensor Characteristics |

AOUT: Analog output signalExample 1: Basic Gas Detection with ArduinoIn this example, we will use the MQ-6 Gas Sensor Module with an Arduino board to detect propane gas and display the concentration on the serial monitor.Hardware RequirementsArduino Board (e.g., Arduino Uno)
MQ-6 Gas Sensor Module
Breadboard and jumper wiresSoftware RequirementsArduino IDECode
```c
const int gasSensorPin = A0; // Analog input pin for MQ-6void setup() {
Serial.begin(9600);
}void loop() {
int sensorValue = analogRead(gasSensorPin);
float gasConcentration = sensorValue (5.0 / 1023.0); // Convert analog value to voltage
gasConcentration = gasConcentration 1000; // Convert voltage to ppm (assuming 5V = 1000 ppm)if (gasConcentration > 300) { // Adjust threshold value as needed
Serial.println("Propane gas detected!");
Serial.print("Concentration: ");
Serial.print(gasConcentration);
Serial.println(" ppm");
} else {
Serial.println("No propane gas detected.");
}delay(1000); // Take readings every 1 second
}
```
Example 2: Gas Detection with Raspberry Pi using PythonIn this example, we will use the MQ-6 Gas Sensor Module with a Raspberry Pi to detect LPG gas and trigger an alarm when the concentration exceeds a certain threshold.Hardware RequirementsRaspberry Pi (e.g., Raspberry Pi 4)
MQ-6 Gas Sensor Module
Breadboard and jumper wires
Buzzer or alarm module (optional)Software RequirementsPython 3.x
RPi.GPIO libraryCode
```python
import RPi.GPIO as GPIO
import time# Set up GPIO mode
GPIO.setmode(GPIO.BCM)# Define pin connections
gasSensorPin = 17 # GPIO 17
buzzerPin = 23 # GPIO 23 (optional)# Set up GPIO pins
GPIO.setup(gasSensorPin, GPIO.IN)
GPIO.setup(buzzerPin, GPIO.OUT, initial=GPIO.LOW)while True:
sensorValue = GPIO.input(gasSensorPin)
if sensorValue:
print("LPG gas detected!")
# Trigger alarm (if connected)
GPIO.output(buzzerPin, GPIO.HIGH)
time.sleep(1)
GPIO.output(buzzerPin, GPIO.LOW)
else:
print("No LPG gas detected.")time.sleep(1) # Take readings every 1 second
```
Note: In both examples, the sensor's analog output is converted to a digital value, which is then used to determine the gas concentration. The threshold values can be adjusted according to the specific application requirements.
