MQ-135 Sensor Air Quality Sensor Hazardous Gas Detection Module


EGP50.00

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
