The MQ135 air quality sensor detects a wide range of harmful gases, including ammonia (NH3), sulfur dioxide (SO2), benzene, and carbon dioxide (CO2). It operates using a metal-oxide semiconductor that changes resistance in response to air pollutants. The sensor provides both analog and digital outputs, making it easy to interface with microcontrollers. It is commonly used in air purifiers, environmental monitoring systems, and industrial pollution detection. The MQ135 is highly sensitive to toxic gases, making it ideal for air quality assessment. It requires a warm-up time for stable readings. The module is compact, reliable, and widely used in IoT-based pollution control systems.
