  • High Sensitivity to LPG, iso-butane, propane
  • Small sensitivity to alcohol, smoke
  • Good sensitivity to Combustible gas in wide range
  • High sensitivity to Propane, Butane, LPG and also response to Natural gas
  • Long life and low cost
  • MQ-6 Gas Sensor Module

    This is a simple-to-use MQ-6 Liquefied Petroleum Isobutane Propane Gas Sensor module, suitable for sensing LPG (composed of mostly propane and butane) concentrations in the air. The MQ-6 can detect gas concentrations anywhere from 200 to 10000ppm.

    This sensor has high sensitivity and a fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

    The sensitive material of the MQ-6 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exists, The sensor’s conductivity is higher along with the gas concentration rising. Please use a simple electro circuit, Convert the change of conductivity to the corresponding output signal of gas concentration.

    MQ-6 gas sensor has a high sensitivity to Propane, Butane, and LPG, also the response to Natural gas. The sensor could be used to detect different combustible gas, especially Methane, which is with low cost and suitable for different applications.

    Applications:

    • Detect or measure Gases like LPG, and butane
    • Air quality monitor
    • Gas leak alarm
    • Safety standard maintenance
    • Maintaining environmental standards  in hospitals

    Frequently Asked Questions

    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).
