How to Use MQ-4 Methane Gas Sensor | Microcontroller Tutorials

· MQ-4 Methane Sensor Overview. At the heart of the MQ-4 is a heater and electrochemical sensor. When the target gas enters the membrane and reaches the sensor, it undergoes a redox reaction which creates current. This current is stronger for sensors at specific gases. In the case of the MQ4, it’s more sensitive to methane, butane and propane. If you are looking to buy a MQ-4 sensor, …

MQ-2 Sensor und Luftqualitäts-Sensor – ein Vergleich ...

· Der Test hier zeigt einen Vergleich zwischen dem Luftqualitäts-Sensor, welcher leider nicht mehr erhältlich ist, und dem MQ-2 in dem selben Raum und dicht nebeneinander gestellt. Einige Meßwerte gingen schief, das lag aber darin, das Zug im Raum war und der MQ-2 falsche Messungen lieferte. Ebenfalls habe ich den MQ-2 immer nur alle 10 min mal messen lassen.

MQ2 Gas Sensor Tutorial for Arduino, ESP8266 and ESP32

· The analog sensor value increases due to the increase of gas concentration. The potentiometer must be calibrated in a way that if there is no relevant gas concentration, the input voltage of the comparator (3) has to be higher than the output voltage of the MQ2 sensor that equals the reference voltage of the comparator (2). In this case, the output of the comparator is equal to VCC and ...
