The sensitivity of the digital pin can be controlled by using the 10k potentiometer. If the gas is detected the indicator LED D0 will turn on and the digital pin will go from logic high to logic low (0V). The LM393 Op-Amp Comparator IC is used to compare the actual gas value with the value set using the potentiometer. If the actual gas value increases than the set value then the digital output pin gets low. \u003c\/span\u003e\u003c\/p\u003e\u003cp class=\"p1\"\u003e\u003cspan class=\"s1\"\u003eBecause of the onboard LM393 comparator IC the MQ135 Gas sensor module can also be used without the need of an external microcontroller.
