MQ-131 Ozone Gas Detection Sensor
Ozone sensors are specifically designed to detect ground-level ozone, a harmful pollutant that can irritate the respiratory system. The MQ131 gas sensor employs a semiconductor metallic oxide as its sensitive material, which exhibits high conductivity in clean air. When ozone gas is present, the sensor’s conductivity decreases in proportion to its concentration. This change in conductivity is then converted into an output signal that correlates with the ozone concentration, thanks to a simple circuit design.
Highly sensitive to ozone, the MQ131 can detect even low levels of the gas. However, it is also responsive to other strong oxidizing agents like chlorine (Cl2) and nitrogen dioxide (NO2), and its output will decrease when exposed to these substances. Additionally, the sensor exhibits an inverse response to organic interference gases.
Our ozone sensors and monitoring systems are widely used in applications ranging from industrial hygiene to virus disinfection and building sterilization, both in commercial and residential settings. They play a vital role in ensuring safe, healthy environments by effectively monitoring ozone levels and other related pollutants.
