With Airthereal ozone generators, we use nature's powerful deodorizer to help with household cleansing. Ozone (O3) contains three atoms of oxygen. The third oxygen atom makes ozone extremely reactive, which readily attaches itself to other molecules. When pollutants meet ozone, oxidation reactions occur and both parties are destroyed.

MQ-9 gas sensor module has high sensitivity to Carbon Monoxide, Methane and LPG. Sensitive material of MQ-9 gas sensor is SnO2, which with lower conductivity in clean air. It makes detection by cycling high and low temperature, and detects CO when low temperature (heated by 1.5V). The sensor's conductivity is higher along with the gas concentration rising.
