Playground Arduino Sensor MQ

Gas Sensor - Ardumotive Arduino Greek Playground

The MQ series of gas sensors use a small heater inside with an electro-chemical sensor. They are sensitive for a range of gasses and are used indoors at room temperature. The output is an analog signal and can be read with an analog input of the Arduino. The MQ-2 Gas Sensor module is useful for gas leakage detecting in home and industry. It can ...

Korrekter Betrieb eines MQ-7 Kohlenmonoxide Sensors

· Korrekter Betrieb eines MQ-7 Kohlenmonoxide Sensors. Hi, ich versuche gerade einen CO-Sensor zu bauen. Wir haben einen Kachelofen und ich würde gerne wissen ob und wie stark die CO Belastung sich im Raum ändert. Laut Schornsteinfeger wird es eine CO-Belastung geben aber bei korrektem Betrieb des Ofens sollte sie vernachlässigbar sein.

Luftqualitätssensor MQ-135 Kallibrieren

· Nun kommt der Sensor nach 24 Stunden auf 500ppm CO2-Anteil. Diese "500" sind Deine Referenz. Weicht der Wert ab (473/523) dann sagst Du dem Arduino "mach was". Es wird also nur verglichen. Willst Du richtig messen, dann brauchst Du eine richtige Referenz. Du brauchst also einen Raum, in dem Du verschiedene Werte simulieren kannst.
