MQ3 Alcohol GAS Sensor

MQ3 GAS Sensor is a very easy to use and very handy sensor. It is suitable for sensing Alcohol gas concentration.  MQ3 Alcohol GAS Sensor can detect  Alcohol  gas concentrations  anywhere  from  200  to 10000 ppm. The MQ3 GAS sensor has a very hight sensitivity to Alcohol gas. The  sensitive  material  of  MQ3 Sensor is  SnO2, which  has  lower  conductivity  in  clean  air. When  the target  alcohol  gas  exist,  the  sensor’s  conductivity  is  higher  along  with  the  gas  concentration rising. MQ3 GAS sensor has high sensitivity to Alcohol, and good resistance to disturb of gasoline, smoke and vapour. The sensor could be used to detect alcohol with different concentration, it is with low cost and suitable for different application.
