{"title":"Carbon Monoxide Sensor - MQ-7","handle":"carbon-monoxide-sensor-mq-7","url":"/products/carbon-monoxide-sensor-mq-7","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.
