Gas Sensor MQ-9 Sensitive Carbon Monoxide (CO) & Flammable Gas

  • Was  RM30.00 
  • RM16.00

  • Product Code: Gas MQ-9
  • Availability: In Stock

MQ9 is a semiconductor sensor which can detect the presence of Carbon Monoxide (CO) gas at concentrations from 100 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 flammable gas. MQ9 Carbon Monoxide  gas sensor can be easily interfaced with Microcontrollers, Arduino Boards, Raspberry Pi etc using an Analog to Digital Converter (ADC).
