16/2/2018· Let’s start by saying that MQ sensors are made of a heating element, named heater, and of an electrochemical sensor; the heater is needed in order to bring the sensor to the proper operational conditions, since only at certain temperatures the sensor’s sensitive surface (typically, a metal oxide) will react, and will let the gases and the particles (the ones we wish to detect) penetrate it.

19/4/2017· Specifications of MQ135 gas sensor. Wide detecting scope. Fast response and High sensitivity. Stable and long life Simple drive circuit. Used in air quality control equipment for buildings/offices, is suitable for detecting. of NH3, NOx, alcohol, Benzene, smoke, CO2, etc. Size: 35mm x 22mm x 23mm (length x width x height) Working voltage: DC 5 V.

The concentration sensing range of 300 ppm to 10,000 ppm is suitable for leak detection. For example, the sensor could detect if someone left a gas stove on but not lit. The sensor can operate at temperatures from 10 to 50°C and consumes less than 150 mA at 5 V. Please read the MQ4 datasheet (161k pdf) for more information about the sensor.

14/4/2015· The problem isn''t the A2D he''s using. The problem is the sensor itself. The sensor detects all the gases it detects all at the same time. It has only one analog output, so only one reading can be taken. Having multiple sensors won''t help either because the sensor cannot be configured as to which gas will be detected. –
