The MQ-2 Smoke LPG Butane Hydrogen Gas Sensor Detector Module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, the measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by the potentiometer.
MQ-2 gas sensor using gas sensitive material is to be clean air in the lower conductivity of tin oxide (SnO2). When the sensor when flammable gases are present in the environment in which the conductivity of the sensor with an increasing concentration of combustible gas in the air increases.
Use a simple circuit to convert the changes in conductivity and output signal that corresponds to the concentration of the gas.
MQ-2 gas sensor higher sensitivity to liquefied petroleum gas, propane, hydrogen, detection of gas and other combustible vapours are ideal. This sensor can detect a variety of flammable gas, is a low-cost sensor for many applications.

Applications of MO2:-
These sensors are used to detect the presence of gases in the air such as methane, butane, LPG and smoke but they are unable to distinguish between gases. Thus, they cannot tell which gas it is.
This sensor is also used for Air quality monitoring, Gas leak alarm and for maintaining environmental standards in hospitals. In industries, these are used to detect the leakage of harmful gases.
It works exactly as specified. It has been working in a highly humid enclosed without any problems. Very consistent readings. Just make sure there are no obstacles in its view other than the surface under measurement.
I recommend the MQ2 Mq-2 LPG Methane Butane Hydrogen Gas Sensor Smoke Detector Module by Robotbanao for your main projects too .You can buy this with 100% guarantee and having a good service from Robotbanao. I enjoyed the purchase and definitely you will also be happy with this.
This is a decent product exactly as shown in the image and works properly as i expected, quality wise also it's the best when compared with the other products available in the market. Fast delivery by Robotbanao.
It was working as expected nice
