Interfacing MQ-2 Gas Sensor with evive - STEMpedia

MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kind of gases combination. They can be calibrated, but, in order to do that, a known concentration of measured gas or gases is needed. In our case, we will test it, as it comes from the producer without any additional calibration. The MQ2 Gas sensor has a built-in variable resistor that ...

Raspberry Pi Gas Sensor (MQ-X) konfigurieren und auslesen

· Falls du einen anderen Sensor als den MQ-2 verwendest und dieser eine andere Spannung hat, muss der Aufbau natürlich angepasst werden. Nachdem der MCP3008 richtig angeschlossen ist, nutzen wir den Port 0 und verbinden ihn an RX0 des TTLs. Auf der gegenüberliegenden Seite befindet sich RX1, welches an den Analog Pin (A0) des MQ2 Sensors kommt. Außerdem wird an den TTL vom Raspberry Pi ...

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
