Jul 10, 2020· The MQ135 is an air quality control sensor which allows the detection of gases such as ammonia, alcohol, benzene, smoke and carbon dioxide with a range of 101000 ppm (parts per million). It is used to prevent high levels of contamination. It is recommended for homes and in industries that handle chemical compounds which can be harmful to health.

Jul 14, 2021· MQ135 sensor. MQ135 is an airquality sensor. It can be used to detect CO2, Nitrogen Oxide, Benzene, NH3, smoke, and alcohol. The load resistance of the sensor can be adjusted to detect a particular gas, smoke, or alcohol. In this project, the MQ135 sensor is used to detect the CO2 …

May 08, 2020· MQ135 Air Quality Sensor. The MQ135 gas sensor senses the gases like ammonia nitrogen, oxygen, alcohols, aromatic compounds, sulfide and MQ3 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.

The MQ135 gas sensor module consists of a steel exoskeleton under which a sensing element is housed. This sensing element is subjected to the current through connecting leads. So, this current is known as the heating current through it, the gases coming close to the sensing element get ionized and are absorbed by the sensing element.

May 12, 2020· Instead of MQ135, you can use MQ2, MQ3, MQ5 module as well. Basically, they all have similar functions. This type of sensor circuit can be used as a breathalyzer to check a person’s bloodalcohol level. Just as we exhale carbon dioxide when we breathe out, we also will breathe out some alcohol if we have alcohol in our blood.

CO2 = 410*ppm* (Rs/f_RH_T / Rs410/f_RH_T_410)^b. Where the exponent b is equal to according to Mad Frog. And where Rs410 is the sensor resistance measured in clean air (410 ppm of CO2) and f_RH_T_410 is the correction factor at the moment that the clean air sensor resistance is measured. Here we assume that the correction factor as a ...
