Product Description

MQ-9 Carbon Monoxide Flammable CO Gas Sensor Module Shield Liquefied Electronic
MQ-9 Sensor Description :

  • Sensitive material MQ-9 gas sensor is used to clean the air in the lower conductivity of tin dioxide (SnO2). Detection method using low temperature cycling (1.5V heating ) to detect carbon monoxide, conductivity sensors with carbon monoxide in the air increased with increasing gas concentration , spurious adsorption at high temperatures (5.0V heating ) detection of combustible gases methane, propane and cryogenic cleaning gases. Simple circuit can be used to change the conductivity , concentration of the gas is converted to the corresponding output signal.
  • MQ-9 high gas sensor for carbon monoxide, methane , liquefied petroleum gas sensitivity , the sensor can detect a variety of gases containing carbon monoxide and flammable , is a low-cost sensors for a variety of applications .

    Module Applications:

    Suitable for home or factory gas leakage monitoring devices , monitoring devices suitable for carbon monoxide and other combustible gases , carbon monoxide can be tested 10 to 1000ppm CO, combustible gas range 100 to 10000ppm

    Module Features :

    1 , using high-quality dual-panel design, with power indicator and TTL signal output instructions;

    2 , the switching signal having a DO (TTL) output and analog output AO ;

    3, TTL output valid signal is low . ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )

    4 , the higher the voltage of the analog output voltage with concentration higher .

    5 , for the carbon monoxide detector has good sensitivity.

    6 , there are four screw holes for easy positioning ;

    7 Product dimensions : 32 (L) * 20 (W) * 22 (H)

    8 , has a long life and reliable stability

    9 , rapid response and recovery characteristics

    Electrical properties:

    Input voltage : DC5V Power consumption ( current ): 150mA

    DO output : TTL digital 0 and 1 ( 0.1 and 5V)

    AO output :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4V
