    Description

    The MQ-131 Ozone Gas Detector Sensor Module is a versatile gas-sensing module designed for detecting ozone (O₃) concentrations in the air with exceptional accuracy and response time. Built around a SnO₂-based sensitive element, the sensor’s conductivity increases with ozone concentration, allowing for precise analog and digital signal output. It supports dual signal modes — analog for continuous measurement and TTL-level digital for threshold-based alerts — making it suitable for integration with Arduino, ESP32, and other microcontrollers. This module is highly responsive to ozone, chlorine (Cl₂), and nitrogen dioxide (NO₂), making it ideal for air quality monitoring, industrial safety systems, and smart environmental stations. The onboard LED indicator provides real-time detection feedback, while mounting holes and a detachable probe simplify installation and maintenance. Designed for reliability and long service life, the MQ-131 is a great choice for detecting trace levels of ozone in various applications. Featured By RoboticsBD.
