This is a simple-to-use Carbon Monoxide (CO) sensorsuitable 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 5Vadd a load resistanceand connect the output to an ADC.
This sensor comes in a package similar to our MQ-3 alcohol sensorand can be used with the breakout board below
