MQ-4 Methane Sensor Circuit Built with an Arduino

The methane sensor circuit we will build with an MQ-4 sensor integrated with an arduino is shown below. The connections are pretty basic. To connect the sensor, there are 4 leads. 2 of them are for power. The +5V terminal of the sensor connects into the 5V terminal of the arduino board. The GND terminal of the sensor connects into the GND terminal of the arduino. This establishes power for the ...

Performance of a low-cost methane sensor for ambient ...

methane sensor used by Tumer and G¨ und¨ uz¨ (2010) is only sensitive to CH4 in the range 1000–10000ppm. To the best of our knowledge, the TGS 2600 is the first sensor for which the manufacturer indicates a sensitivity to methane even in the ppm range (Fig. 1a). Besides methane, a sensitivity to car- bon monoxide, iso-butane, ethanol and hydrogen is reported by the manufacturer …

Nanocrystalline Metal Oxides for Methane Sensors: Role of ...

Methane is an important gas for domestic and industrial applications and its source is mainly coalmines. Since methane is extremely inflammable in the coalmine atmosphere, it is essential to develop a reliable and relatively inexpensive chemical gas sensor to detect this inflammable gas below its explosion amount in air. The metal oxides have been proved to be potential materials for the ...
