MQ-135 Sensor Air Quality Sensor Hazardous Gas Detection Module
Internal Reference:
KIT.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 by 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 detecdetect 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.
