MQ-9 carbon monoxide, combustible gas sensor detection alarm module

Product description:

  • Sensitive material of MQ-9 gas sensor is SnO2, which with lower conductivity in clean air. It make
    detection by method of cycle high and low temperature, and detect CO when low temperature (heated
    by 1.5V). The sensor’s conductivity is more higher along with the gas concentration rising. When high
    temperature (heated by 5.0V), it detects Methane, Propane etc combustible gas and cleans the other
    gases adsorbed under low temperature. Please use simple electrocircuit, Convert change of conductivity
    to correspond output signal of gas concentration.
  • MQ-9 gas sensor has high sensitity to Carbon Monoxide, Methane and LPG. The sensor could be
    used to detect different gases contains CO and combustible gases, it is with low cost and suitable for
    different application.

Features:

  • Good sensitivity to CO/Combustible gas
  • High sensitivity to Methane, Propane and CO
  • Long life and low cost
  • Simple drive circuit

Application:

  • Domestic gas leakage detector
  • Industrial gas detector
  • Portable gas detector
