Gassensor – Wikipedia

Der Sensor war in der Lage, noch Konzentrationen an TNT in Luft von weniger als einem ppt innerhalb von 3 Minuten nachzuweisen. Eine praktische Verwendung dieser Sensoren für ein selektives Detektorsystem für Sprengstoffe oder andere Gase steht noch aus. Ein anderes Verfahren basiert auf sogenannten Gold-Mesoflowers, ca. 4 µm große Goldpartikel, die mit Siliciumdioxid beschichtet sind …

Air Analyzer, Using Almost All Kinds of MQ Sensors ...

· So I ordered a set of 9 MQ sensors and made this project, in which I can measure the concentration of many kinds of gas in the air only using some MQ sensors. This kind of sensor is not so accurate and needs lots of calibration, but they are the best cheap gas sensors out there. You can find a set of nine gas sensors for only $6 to $7. in my project, I use 6 of them and measure the gas ...
