Product Descrption:

  • Main Chip: LM393, ZYMQ-5 gas sensor
  • Operating Voltage: DC 5V
  • Input Voltage: DC5V
  • Power: 150mA
  • DO Output: 0.1V/5V
  • AO Output: 0.1-0.3



  • Indication of the signal output
  • Dual signal output (analog output, and TTL level output)
  • TTL output signal is low. (When low output signal light, and can be connected directly to the microcontroller)
  • 0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage
  • Liquefied petroleum gas, natural gas, city gas, better sensitivity
  • Has a long life and reliable stability
  • Fast response and recovery characteristics
