Hello learners! I hope you are doing good. Today, we are learning about an important member of the gas sensor family, which is the MQ-2. When it comes to detecting or measuring smoke or gas, the MQ series gas sensors are widely used components in circuits. These sensors come with an operational amplitude comparator and a digital output pin therefore, they have applications in multiple fields of life. Mostly, it is used in Arduino projects where it senses the gas and the information is fed into the Arduino to allow the circuit to work according to its digital output.
In this article, we are g ...
