Smoke Detector using MQ2 Gas Sensor and Arduino

Smoke Detector using MQ2 Gas Sensor and Arduino

Smoke Detectors arevery useful in detecting smoke or fire in buildings, and so are the important safety parameters. In this DIY session, we are going to build a Smoke Detector Circuit which not only sense the smoke in the air but also reads and displays the level of Smoke in the Air in PPM (parts per million).

Interfacing MQ2 to Arduino- Gas Sensor for Smoke-Butane-CH4 and LPG

In this article, we are going to learn how to interface MQ2 Gas Sensor with Arduino. MQ2 is basically a general purpose gas sensor (similar to MQ5) which can sense a broad range of gases like LPG, Butane, Methane(CH4), Hydrogen and in addition to these gases MQ2 is sensitive to smoke as well. In a
