MQ -135 Gas Sensor

It is a hazardous gas detection apparatus for the family, the environment, suitable for ammonia, aromatic compounds, sulphur, benzene vapour, smoke and other gases harmful gas detection, gas-sensitive element test.

Air quality sensor is for detecting a wide range of gases, including NH3, NOx, alcohol, benzene, smoke and CO2. Ideal for use in office or factory with simple drive and monitoring circuit.

Features

• Dual signal output (analog output, and TTL level output)
• TTL output valid signal is low
• Analog output with increasing concentration, the higher the concentration, the higher the voltage
• Sulphide, benzene, smoke and other harmful gases with high sensitivity
• Has a long life and reliable stability
• Rapid response recovery characteristics
