The MQ135 Gas sensors are used in air quality control systems and are suitable for detecting gases such as CO2, Smoke, NH3, NOx, Alcohol, Benzene, etc.
MQ2 is one of the commonly used gas sensors in MQ sensor series. It is a Metal Oxide Semiconductor (MOS) type Gas Sensor also known as Chemiresistors as the detection is based upon change of resistance of the sensing material when the Gas comes in contact with the material. Using a simple voltage divider network, concentrations of gas can be detected. MQ2 Gas sensor works on 5V DC …
20160529· Le MQ135 est donc un capteur de gaz ( dans mon cas je voudrais capté le CO2) mais je sais pas trop comment le calibré, je souhaite faire l''acquisition avec une carte arduino ..... j''ai lue quelque part qu''il fallait le laissé 24h sous tension avant la première utilisation, sur un autre site j''ai lu qu''il fallait d''abords exécuté un programme puis le laissé 24h sous tension alors sv si ...
20170501· Hello, the MQ135 is not a smoke sensor. You can use it as a smoke sensor, but something like the MQ2 is preferred. Instead of using the correlation function you can set a thresold on the ADC raw value you read on your Arduino. You can also use an opamp as a comparator, and set the threshold for your smoke detection. Delete
