MQ135 Air Quality sensor for ArduinoAir quality sensor for detecting a wide range of gases, including NH3, NOx, alcohol, benzene, smoke, and CO2. Ideal for use in office or factory. MQ135 gas sensor has a high sensitivity to Ammonia, Sulfide, and Benze steam, also sensitive to smoke and other harmful gases. It is at low cost and particularly suitable for Air quality monitoring applications.Features :Sensitivity to Ammonia, Sulphide, and Benzene steamWith signal output instructionsThe TTL output signal is a low levelAnalog 0 ~ 5 v voltage output, the higher the concentration, the higher the voltageColor is showing pictures.Sensitive for benzene, alcohol, smokeFast response and recoveryAdjustable sensitivitySignal output indicatorOutput voltage boosts along with the concentration of the measured gases increases.
