MQ 2 Gas Sensor - IoCT

form the sensing system. When the gas interacts with the sensor, the heat from the system ionizes the gas. This ionization allows SnO 2 to absorb the gas. This adsorption causes a change in the resistance on the sensor. The output legs then send this resistance as an output signal to the ,5 Connecting the MQ 2 Figure A0 VCC GND Stainless-Steel Mesh 3: Anti -Explosion Mesh on ...

Fire, Gas and Smoke Detector - Arduino Project Hub

In this project the MQ2 and flame sensor simultaneously collect data from the environment and then transfer it to the arduino board in the form of analog inputs. The arduino board then checks if the values submitted by the sensors is less or more than that of the value kept constant in the memory. If the value is higher or lower than the threshold value the arduino acts respectively. When ...
