Detailed Description :

  • The main chip: LM393, MQ135 gas sensing probe
  • Operating voltage: DC 5V


Feature :

  •  Signal output indicator instructions;
  •  Dual signal output (analog output, and TTL level output);
  •  TTL output valid signal is low; (output low signal light, which can be    accessed microcontroller IO port)
  •  Analog output with increasing concentration, the higher the concentration,  the higher the voltage;
  •  Sulfide, benzene Department of steam, smoke and other harmful gases  with high sensitivity;
  •  Has a long life and reliable stability;
  •  Rapid response recovery characteristics;

Application :

   A hazardous gas detection apparatus for the family, the environment, suitable for ammonia, aromatic compounds, sulfur, benzene vapor, smoke and other gases harmful gas detection, gas-sensitive element test concentration.

    Air quality sensor is for detecting a wide range of gases, including NH3, NOx, alcohol, benzene, smoke and CO2. Ideal for use in office or factory, simple drive and monitoring circuit.
