MQ-4 Methane Sensor Circuit Built with an Arduino

MQ-4 Methane Sensor Circuit Built with an Arduino. In this project, we will go over how to build a methane sensor circuit with an arduino. The methane sensor we will use is the MQ-4 sensor. This is a sensor that is sensitive to effects of methane. Methane (CH 4) is a colorless, odorless gas with a wide distribution in nature.
