Air Quality Sensor Module MQ-135

• Sensitive for benzene, alcohol, smoke
• Output voltage boosts along with the concentration of the measured gases increases
• Fast response and recovery
• Adjustable sensitivity
• Signal output indicator

• Operating voltage: DC 5V
• Power (current) : 150mA
• DO Output: 0.1V/5V
• AO Output: 0.1-0.3V
• 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
• Applications:
• 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 range: 10 to 1000pp
