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 …

How to Build a MQ-2 Smoke Sensor Circuit with a Raspberry Pi

The gas sensor needs about 5 volts of power in order to operate. This is done by connecting 5 volts to Vcc and GND. The Output pin gives out the voltage reading, which is proportional to the amount of smoke that the sensor is exposed to. Again, a high voltage output means the sensor is exposed to a lot of smoke. A low or 0 voltage output means the sensor is exposed to either little or no smoke ...
