Interfacing of MQ135 Gas Sensor with Arduino

What is MQ135 gas sensor and how does it work? The gas sensor module consists of a steel exoskeleton under which a sensing element is housed. This sensing element is subjected to current through connecting leads. This current is known as heating current through it, the gases coming close to the sensing element get ionized and are absorbed by the sensing element. This changes the resistance of the sensing …

How To Use MQ135 Gas Sensor Codrey Electronics

· The MQ135 gas sensor has an inbuilt variable resistor (sense resistor) that changes its resistance value according to the concentration of gas. If the gas concentration is high, the resistance decreases, and if the gas concentration is low, the resistance increases. The MQ135 gas sensor basically needs only one key component as the external component – just a load resistor. The load resistor serves to adjust the sensor’s …
