How to Use MQ2 Gas Sensor Arduino Tutorial : 4 Steps ...

+

The MQ series of gas sensors use a small heater inside with an electrochemical 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 MQ2 Gas Sensor module is useful for gas leakage detecting in home and industry. It can detect LPG, ibutane, propane, methane ,alcohol ...

MQ135 Gas Sensor Pinout, Features, Alternatives ...

+

20180227· MQ135 gas sensor applies SnO2 which has a higher resistance in the clear air as a gassensing material. When there is an increase in polluting gases, the resistance of the gas sensor decreases along with that. To measure PPM using MQ135 sensor we need to look into the (Rs/Ro) v/s PPM graph taken from the MQ135 datasheet. The above figure shows shows the typical sensitivity …

20170117· For the MQ135 you can only connect it to pin A0, as this is the only analog pin on the ESP8266. For the air quality I store the lowest measured value in the EEPROM, so anything worse/higher that this best value is bad air quality. I use variable a1 a2 a3 to check if it is an new ESP8266, if these value in EEPROM are different than the stored values I presume that it is a new ESP and then ...
