The MQ4 sensor is a compact gas sensor which is highly sensitive to methane gas and less prone to alcohol and other gases. This methane gas sensor provides an output signal according to the sensed concentration of CH4 in the surrounding or environment. This sensor is proved to be effective in alarm systems, gas detection circuits whether at a commercial level or in coal mines, etc.
There are LPG cylinders which are used as a fuel source for the gas stove. Many a times, disastrous accidents take place due to leakage of these cylinders, in these situations we must administer proper care and safety. Keeping this in mind, in today’s post I have worked on MQ2 gas sensor (FC22) powered and interfaced with Arduino Uno.

We can connect these devices to an automaton or processor like Arduino. There is a wide variety of MQ sensors. Each model is designed to detect one or more substances, designed for a specific use, such as detection of flammable gases, air quality or detection of alcohol in breathed air. MQ gas sensors are usually provided with a standard measuring plate with the comparator LMC662 or similar ...
21/08/2020· This gas sensor uses a MQ2 gas sensor to indicate if there is gas in the area. so the sensor has a threshold value (the threshold value is around the amount of smoke in there is a fire) in that if it goes above it starts alerting people in the vicinity. The alert just shows a red led and starts beeping. This idea is very helpful and is used on a daily basis with the smoke alarms that a lot of ...
18/10/2016· Gas Sensor Arduino Hookup. As per the wiring diagram, the MQXX series sensor can be connected with Arduino board. The resistor (10K) connected with B pin to Gnd to maintain sensitivity level of Gas sensor at particular point, if you need variable sensitivity from your sensor you can use variable resistor instead for 10K. A and H pins are connected together with +5V power source pin of …
