MQ9 ( MQ 9 ) gas sensor has high sensitity to Carbon Monoxide, Methane and LPG. This sensor could be used to detect different gases contains CO and combustible gases.

This Carbon Monoxide and flammable gas sensor detects the concentrations of CO and combustible gas in the air and ouputs its reading as an analog voltage. The sensor can measure concentrations of CO from 10 to 1,000 ppm and flammable gas from 100 to 10,000 ppm.The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V.
