The MQ-131 ozone gas sensor utilizes a metallic oxide semiconductor (MOS) sensing element. Its conductivity decreases in the presence of ozone gas, a change that is linearly proportional to the gas concentration. This change is converted into a readable analog voltage signal via an onboard load resistor, enabling straightforward integration with analog-to-digital converters (ADCs) on microcontrollers.
Designed for environmental monitoring, the sensor requires a preheating period for initial stabilization and a brief warm-up before each use to ensure accurate readings. Its construction offers stability across a specified range of temperature and humidity conditions, making it suitable for indoor air quality assessment and industrial safety applications where ozone detection is critical.
