Hi Steve,

I meant to ask what the sensor was connected to; i.e., what kind of control board. Seems these gas sensors require a control board of sorts to calibrate and to drive the heat circuit. Here's something to take a look at: http://www.futurlec.com/Gas_Sensors.shtml and this: http://learn.parallax.com/carbon-monoxid...duino-demo and this: http://www.ebay.com/itm/MQ-7-Gas-Sensor-...0772999740

As you can see you need to electronically drive them.
