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 the MQ-8 sensor, and can be used with the breakout board below.
