Gas Sensor MQ-5 Sensitive Natural Gas LPG Goal

  • Was  RM22.00 
  • RM12.00

  • Product Code: Gas MQ-5
  • Availability: In Stock

MQ5 is a semiconductor sensor which can detect the presence of LPG, Natural and Coal gases at concentrations from 200 to 10,000 ppm. The sensitive material used for this sensor is SnO2, whose conductivity is lower in clean air. It’s conductivity increases as the concentration of sensing gases increases. It has also some sensitivity to smoke and alcohol. MQ5 LPG natural gas sensor module can be easily interfaced with Microcontrollers, Arduino Boards, Raspberry Pi etc.



  • Low Cost
  • High Sensitivity to LPG, Natural Gas and Town Gas
  • Fast Response
  • Stable and Long Life
  • Simple drive circuit
  • Analog and Digital Outputs
  • Trigger Level configuration Potentiometer
