GAZ SENSOR (MQ135)

GAZ SENSOR  -  MQ135

Detailed Description:

• The main chip: LM393, MQ135 gas sensing probe
• Operating voltage: DC 5V

Sensitive gas:

Ammonia, nitrogen oxide, alcohols, aromatic compounds, sulfide and smoke 

Feature:

• Signal output indicator instructions.
• Dual signal output (analog output, and TTL level output).
• TTL output valid signal is low; (output low signal light, which can be accessed microcontroller IO port).
• Analog output with increasing concentration, the higher the concentration, the higher the voltage.
• Sulfide, benzene Department of steam, smoke and other harmful gases with high sensitivity.
• Has a long life and reliable stability.
• Rapid response recovery characteristics

Application:

A hazardous gas detection apparatus for the family, the environment, suitable for ammonia, aromatic compounds, sulfur, benzene vapor, smoke and other gases harmful gas detection, gas-sensitive element test concentration.

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, simple drive and monitoring circuit.
