MQ-8 gas sensor using gas-sensitive material is to be clean air in the lower conductivity of Tin oxide ( SnO2 ). Use a simple circuit to convert the changes in conductivity and output signal that corresponds to the concentration of the gas. This sensor can detect a variety of hydrogen gas. 


  • Main chip: the LM393, MQ-8 gas sensor Working voltage: DC5V
  • Dual signal output (TTL level output and Analog output)
  • TTL output valid signal for low level.
  • Can be resistant to ethanol steam, LPG (petroleum), smoke interference
  • Has a long service life and reliable stability
  • Quick response recovery features
