It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by potentiometer.\u003c\/p\u003e\r\n\r\n\u003cp\u003eMQ-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 sensors conductivity with 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.\u003c\/p\u003e\r\n\r\n\u003cp\u003eMQ-2 gas sensor higher sensitivity to liquefie\u003cspan class=\"redactor-selection-marker\"\u003e\u003c\/span\u003ed petroleum gas, propane, hydrogen, detection of gas and other combustible vapors are ideal.
