MQ-6 Gas Sensor Module
The MQ-6 gas sensor module is a simple and easy-to-use device designed to sense LPG, composed mainly of propane and butane, concentrations in the air. With a sensitivity range from 200 to 10,000ppm, the MQ-6 gas sensor is suitable for a range of applications.
The MQ-6 gas sensor has high sensitivity and fast response times. The sensor's output is an analog resistance, and the drive circuit is uncomplicated, requiring only a 5V power source to the heater coil, a load resistance, and a connection to an ADC.
The MQ-6 gas sensor employs SnO2 as its sensitive material, which has low conductivity in clean air. As the concentration of target combustible gas increases, the sensor's conductivity rises correspondingly. By using a simple electro circuit, the change in conductivity can be converted into a corresponding gas concentration output signal.
This gas sensor is highly sensitive to propane, butane, and LPG, as well as natural gas. The sensor can detect different combustible gases, particularly methane, and is suitable for various applications due to its low cost.
Features
- Operating Voltage is +5V
- Can be used to detect LPG or Butane gas
- Analog output voltage: 0V to 5V
- Digital Output Voltage: 0V or 5V (TTL Logic)
- Preheat duration 20 seconds
- Can be used as a Digital or analog sensor
- The Sensitivity of Digital pin can be varied using the potentiometer
Applications:
- Detect or measure Gases like LPG, and butane
- Air quality monitor
- Gas leak alarm
- Safety standard maintenance
- Maintaining environmental standards in hospitals
Also check the mq135 gas sensor, which is a versatile device designed for detecting gases like ammonia, sulfur dioxide, and carbon monoxide.

1. What are gas sensors? How do they work?
- Gas sensors (also known as gas detectors) are electronic devices that detect and identify different types of gasses. They are commonly used to detect toxic or explosive gasses and measure gas concentration.
Gas sensor detects the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type and concentration of the gas can be estimated.
2. How to use MQ-6 Gas Sensor?
- Power the module with 5V and you should notice the power LED on the module to glow and when no gas it detected the output LED will remain turned off meaning the digital output pin will be 0V. Remember that these sensors have to be kept on for pre-heating time before you can actually work with it. Now, introduce the sensor to the gas you want to detect and you should see the output LED to go high along with the digital pin, if not use the potentiometer until the output gets high. Now every time your sensor gets introduced to this gas at this particular concentration the digital pin will go high (5V) else will remain low (0V).
