MQ-135 Gas Sensor Luftqualität Modul – AZ-Delivery

The MQ-135 measures a gas concentration of 10 to 1000ppm and is ideal for detecting a gas leak, as a gas alarm or for other robotics and microcontroller projects. The SENSORS of the MQ series use a small heating element with an electronic-chemical sensor. They are sensitive to a wide range of gases and are suitable for use in rooms.

MQ135 Arduino library | Details |

· The datasheet claims that the MQ135 is sensitive for CO2, Alkohol, Benzene, NOx, NH3 and the Fig 3 shows the change in resistance depending on the concentration of these gases in the ambient air in ppm (of the total gas volume). It turns out the the general sensitivity is the roughly same for all the gases. This is where you think: Wait a minute! CO2 is the 4th most abundant trace gas in the ...

MQ gas sensor correlation function estimation by datasheet

· As a reference, let's consider the MQ135 sensor (again). We will look at the "sensitivity characteristics of the MQ-135" figure of the datasheet. Notice that it's a log-log plot, this means that is has logarithmic scales on both axes. Another thing to notice, is that the y-axis is for Rs/Ro, it will be much clearer if we impose ppmon the y-axis.

Measuring CO2 with MQ135 – Pocket Science Lab

· The MQ135 data sheet does not specify response curves for any reducing gases, so while the sensor should be sensitive to such gases, the user would have to experimentally determine the response curves themselves. [Shimizu] MQ135 gas response curves. The MQ135 data sheet provides a graph showing how the sensor resistance changes with the concentration of several gases. Figure 1 …
