Package Includes: 1 piece x MQ 2 SMOKE Detector and Flammable Gas Sensor


MQ2 Gas Sensor is useful for gas leakage detecting(in home and industry). It can detect LPG, i-butane, methane, alcohol, Hydrogen, smoke and so on. Based on its fast response time. measurements can be taken as soon as possible. Also the sensitivity can be adjusted by the potentiometer. 


MQ2 gas Sensor can  detect  gas concentrations  anywhere  from  200  to  10000ppm.  MQ2 sensor  is very sensitive to Propane, Hydrogen, methane and LPG. 


The MQ series of gas sensors use a small heater inside with an electro-chemical sensor. They are sensitive for a range of gasses and are used indoors at room temperature. 


The  sensitive  material  of  MQ2 Gas sensor is  SnO2, which  has  lower  conductivity  in  clean  air. When  the target gas exist, the sensor’s conductivity is higher along with the gas concentration rising.  MQ2 sensor  could  be  used  to  detect  different combustible  gases  especially  Methane.  It  is  very  low cost and suitable for different application. This sensor can be used to make wireless Gas leak detector in home security system.
