RAM Electronics's Description
This is a simple-to-use Carbon Monoxide (CO) sensor, suitable for sensing CO
concentrations in the air. The MQ-7 can detect CO-gas concentrations anywhere
from 20 to 2000ppm.
This sensor has a high sensitivity and fast response time. The sensor's
output is an analog resistance. The drive circuit is very simple; all you need
to do is power the heater coil with 5V, add a load resistance, and connect the
output to an ADC.
This sensor comes in a package similar to our MQ-3 alcohol sensor, and can
be used with the breakout board below.
