Smoke Sensor MQ2

86

MQ-2 gas sensor has high sensitity to LPG, Propane and Hydrogen, also could be used to Methane and other combustible steam, it is with low cost and suitable for different application.

  • Type - Analog Sensor.
  • Operating Voltage - 3.3 - 5V.
  • Output Voltage is proportional to the concentration of the Smoke
  • Output Voltage is proportional to the concentration of the Smoke

Sensitive material of MQ-2 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration. MQ-2 gas sensor has high sensitity to LPG, Propane and Hydrogen, also could be used to Methane and other combustible steam, it is with low cost and suitable for different application. Character :*Good sensitivity to Combustible gas in wide range * High sensitivity to LPG, Propane and Hydrogen * Long life and low cost * Simple drive circuit... Application :* Domestic gas leakage detector * Industrial Combustible gas detector * Portable gas detector

MQ-2 gas sensor has high sensitity to LPG, Propane and Hydrogen, also could be used to Methane and other combustible steam, it is with low cost and suitable for different application.
