    A sensitive material MQ-8 Hydrogen Gas Sensor Module H2 Alarm Detection use in clean air low conductivity tin oxide (SnO2). When there is the environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases.

    Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-8 hydrogen gas sensor of high sensitivity, the monitoring of the other hydrogen-containing gas is also very satisfactory.

    This sensor can detect a wide range of hydrogen gas, city gas, in particular, is a low-cost sensor for a variety of applications.

    Suitable for home or industrial hydrogen leakage monitoring devices. Can not interfere with ethanol vapor, soot, carbon monoxide, and other gases.

    1. Using high-quality double panel design, it has a power indication and TTL signal output indication. 
    2. It has DO switching signal (TTL) output and AO analog signal output. 
    3, the TTL output effective signal is low level. (when the output is low, the signal lights on, can be directly connected to a single chip or a relay module). 
    4. To simulate the output voltage, the higher the concentration, the higher the voltage. 
    5. It has good sensitivity to the detection of hydrogen. 
    6, four screw holes are easy to locate; 
    7. The shape of the product: 32 (L) *20 (W) *22 (H) 
    8. Long-term life and reliable stability 
    9. Fast response recovery characteristics 

    Electrical performance: 
    Input voltage: DC5V power consumption (current): 150mA 
    DO output: TTL digits 0 and 1 (0.1 and 5V) 
    AO output: 0.1-0.3V (relatively pollution-free)
