Gassensor – Wikipedia

Problematik chemischer Sensoren. Das Gebiet der chemischen Sensoren ist relativ jung. Während Sensoren zum Messen physikalischer Größen wie beispielsweise Temperatur, Druck und Beschleunigung wasser- und luftdicht verschlossen sind, steht ein chemischer Sensor wie der Gassensor in direkter Wechselwirkung mit seiner Umgebung. Dadurch ist er auch wesentlich …

IoT Gas Sensor with ESP8266 – EF Computer

· We will check the sensor via analog to give much better variation, we can also use the Digital output from the sensor, but you will have to calibrate this properly to ensure that it gives the desired trigger when a certain composition of gas was detected. You can use the prototype board to connect them all up and using Arduino interface you can load the code.
