The MQ-135 air quality sensor is extremely sensitive to ammonia, sulfide, bernze, smoke, and other harmful gas. The resistance of the sensitive component changes as the concentration of the gas changes making it ideal for air quality control applications. The tested co0ncentration range from 10 to 1000ppm.
