CO (Carbon Monoxide) Gas Sensor Using the Arduino Uno

20140329· This simple project uses the Arduino Uno and the MQ7 Gas Sensor to sense the concentration of CO (Carbon Monoxide) in the air. The MQ7 requires a heater voltage that cycles between 5v (60s) and (90s), drawing approximately 150mA at 5v which exceeds the power capacity of the Uno, so I use the KA278RA05C adjustable voltage regulator to drive this.
