MQ-7 Carbon Monoxide Sensor Breakout Board - (AD12591)

Description:

This is a simple carbon monoxide (CO) sensor, suitable for detecting CO concentrations in the air. The MQ-7 can detect CO gas concentrations anywhere from 20 to 2000 ppm.

This sensor has high sensitivity and a fast response time. The sensor output is an analog resistor. The drive circuit is very simple; all you need to do is supply 5V to the heater coil core. It has a comparator circuit that enables the board to have both an analog and a digital output.
