MQ4 Methane Sensor Circuit Built with an Arduino

This is because methane, when burned, emits less carbon dioxide than coal. Carbon dioxide, CO 2, is a dangerous greenhouse gas. However, when unburned, when it is vented or leaked directly into the atmosphere, methane is far more potent than carbon dioxide. In terms of its contribution to global warming, it is 23 times more powerful than carbon dioxide. Thus, methane is a powerful gas that can ...
