MQ-135 is a simple solution to add a high sensitivity sensor to detect a variety of gases that affect air quality in homes and offices. It is designed to work with a 5V power supply. This sensor is suitable for detecting ammonia (NH3), nitrogen oxides (NOx), benzene, smoke, CO2 and other noxious or poisonous gases that affect air quality. The MQ-135 sensor has a sensor layer made of tin dioxide (SnO2), an inorganic compound that has a lower conductivity in clean air than when polluting gases are present.
