Mq2 Gas Sensor Circuit Diagram. Mq2 gas smoke sensor is a very user friendly sensor and it can be easily interfaced with the arduino uno or mega using male to female type jumper wires. Keeping this in mind in today s post i have worked on mq 2 gas sensor fc 22 powered and interfaced with arduino uno.
When we turn on the system s power supply at the same time the mq2 gas sensor starts to sense the smoke level in the air and it gives the output value to the arduino. The mq series of gas sensors use a small heater inside with an electro chemical sensor. When it comes to measuring or detecting a particular gas the mq series gas sensors are the most commonly used ones.

They are sensitive for a range of gasses and are used indoors at room temperature. Mq 6 aq 2 mq 306a aq 3. Many a times disastrous accidents take place due to leakage of these cylinders in these situations we must administer proper care and safety. When it comes to measuring or detecting a particular gas the mq series gas sensors are the most commonly used ones.
