IoT Based Air Quality Index Monitoring with ESP8266 & MQ135

08/05/2020· MQ135 Air Quality Sensor. The MQ-135 gas sensor senses the gases like ammonia nitrogen, oxygen, alcohols, aromatic compounds, sulfide and MQ-3 gas sensor has a lower conductivity to clean the air as a gas sensing material. In the atmosphere, we can find polluting gases, but the conductivity of the gas sensor increases as the concentration of polluting gas increases.

Indoor Air Quality | Sensirion

Possible solutions might include disconnection of the sensor from the heating element by adding slits into the PCB, or connecting the sensor only with narrow bridges to the rest of the PCB. Make sure the sensor is not mounted directly on to heat sources or heat sinks. Reduce sampling. Shorten the cables and/or use a decoupling capacitor (typ. 100nF) between VDD and GND pins of the sensor as ...
