The MQ-135 Gas Sensor Module is designed to detect a variety of gases, including ammonia (NH3), sulfur dioxide (SO2), and carbon monoxide (CO). It utilizes a metal oxide semiconductor (MOS) sensor, which detects gases by measuring changes in conductivity when exposed to the target gas. 

The MQ-135 sensor operates with a low-cost, simple electronic circuit and features a sensitive material, SnO2, that has lower conductivity in clean air. When hazardous gases are present, the conductivity increases, and the sensor outputs a corresponding gas concentration signal.

With high sensitivity to ammonia, benzene vapors, smoke, and other harmful gases, the MQ-135 is suitable for various applications, including air quality monitoring in both industrial and commercial environments. It meets strict industry standards, ensuring reliable and accurate readings of dangerous gases such as carbon monoxide (CO), hydrogen sulfide (H2S), and nitrogen dioxide (NO2). 

The sensor is durable and can be used in both indoor and outdoor settings, making it versatile for long-term operation without compromising performance. The MQ-135 sensor is easy to install and provides quick, dependable data, giving users peace of mind in detecting hazardous gases.
