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

· If we suppose to measure the concentration level as for the carbon monoxide, via a MQ-7 sensor, the gas level might be misrepresented because of the presence (or absence) of other gases the sensor reacts to (such as, for example, the hydrogen). However, the limited cost of the sensor makes it very useful for many projects, so that we may disregard such a detail. Listing2. #plot fitrev curve (l
