How to Calibrate And Use MQ9 Gas Sensor w/ Arduino

The MQ9 sensor is sensitive to carbon monoxide and flammable gases. It can detect the detect carbon monoxide density from 10ppm to 1000ppm and flammable gases density from 100ppm to 10000ppm. MQ9 has an internal heater which starts warming up if a 5V voltage is applied. The internal resistance of this sensor changes as the density of the ...

Presenting MQ sensors: low-cost gas and pollution ...

Feb 16, 2018· Features of the MQ sensors. Most sensors of the MQ series operate with working voltages that are typically at 5V, and have a lower absorption of 1 watt (5V here means less than 200 milliampere); such an absorption is mainly due to the heating element drawing power. As for some MQ sensors, the heater is powered at 2V: a low and atypical voltage ...
