MQ131 Ozone Gas Sensor Module — O3 Detection IRF1407 mosfet Under-voltage lockout (UVLO) — preventsMQ131 Ozone Gas Sensor Module O3 Detection The MQ131 is a semiconductor gas sensor specifically designed to detect ozone (O3) concentration in the air. It uses a tin dioxide (SnO2) sensing element whose resistance changes in the presence of ozone. With both analog and digital outputs, it integrates easily with Arduino, ESP32, and other microcontrollers for air quality monitoring and ozone safety systems.
