The MQ-7  is a low cost, but extremely valuable carbon monoxide (CO) sensor.  It is highly sensitive to concentrations of  CO, detecting it in concentrations as low as 10 ppm. The module outputs this reading as an analog voltage. The sensor consumes less than 150 mA at 5 V and is very stable and has a long life.  It is ideal for use in a CO alarm.
