Presenting MQ sensors: lowcost gas and pollution ...

Feb 16, 2018· Let’s discover a set of lowcost gas and pollution detectors that may be easily accessed from the Arduino World. Detecting and measuring pollution and the main gases (the ones we may come across in our daily life) is always relevant; such operations are carried out by means of specific sensors, that are often very expensive.

MQ2 Flammable Gas and Smoke Sensor HobbyTronics

The MQ2 Flammable Gas and Smoke Sensor detects the concentration of flammable gas and smoke in the air and ouputs its reading as an analog voltage. The concentration sensing range of 300 ppm to 10,000 ppm is suitable for leak detection. The sensor can operate at temperatures from 10 to 50°C and consumes less than 150 mA at 5 V.

Interfacing MQ2 to ArduinoMQ2 Gas and Smoke Sensor

Feb 23, 2016· Similarly MQ2 is sensitive to smoke where as MQ5 is not that sensitive to smoke. So we can not choose MQ5 gas sensor to design a smoke alarm or smoke involving applications. MQ2 can sense methane(CH4) upto 20000 ppm where as MQ5 can sense CH4 only upto 10000 ppm. The difference between MQ5 and MQ2 therefore lies in its range of values.
