LM393，ZYMQ - 2 smoke gas sensor Arduino board

• LM393,ZYMQ - 2 smoke gas sensor Arduino board

  A) long Dimensions: 32mm x width 22mm X high-27mm
  2) Main chip: LM393, ZYMQ-2 gas sensor
  3) Working voltage: DC 5 V
  Features:
  1) indication of the signal output.
  2) Dual output (analog output and TTL-level output)
  3) TTL output valid signal is low. (Output low when the signal light can be directly connected to the microcontroller)
  4) Analog Output 0 ~ 5V voltage, the higher the concentration the higher the voltage.
  5) liquefied petroleum gas, natural gas, city gas have better sensitivity.
  6) has a long life and reliable stability
  7) Quick response and recovery characteristics
  Application:
  
  For the home or factory gas leakage monitoring devices, suitable for liquefied petroleum gas, butane, propane, methane, alcohol, hydrogen gas, smoke and other monitoring devices.
  
  Applicable occasion: SCM learning, electronic competition, product development, graduation design. . .
