The sensing material of the MQ-9B is SnO2, which has a low conductivity in clean air. It detects carbon monoxide (1.5V) by method of cycling high and low temperature. The sensor�s conductivity gets higher with the CO and CH? gas concentration rising. The sensing range is 10-500ppm CH?. A simple circuit makes measuring this change in conductivity and turning it into data fairly straight-forward, but does require some calibration.\u003c\/p\u003e \u003cp\u003eFor easy Solderability; use our \u003ca href=\"https:\/\/www.sparkfun.com\/products\/8891\"\u003eGas Sensor Breakout Board\u003c\/a\u003e.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/d\/f\/5\/e\/2\/MQ-9B_Ver1.4__-_Manual.pdf\"\u003eDatasheet\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eVideos\u003c\/strong\u003e\u003c\/p\u003e \u003cdiv class=\"flex-video-wrap clearfix\"\u003e \u003cdiv class=\"flex-video widescreen img\"\u003e \u003ciframe src=\"https:\/\/www.youtube.com\/embed\/XHoOtEGetJc\/?autohide=1\u0026amp;border=0\u0026amp;wmode=opaque\u0026amp;enablejsapi=1\" frameborder=\"0\" allowfullscreen width=\"560\" height=\"315\"\u003e\u003c\/iframe\u003e \u003c\/div\u003e \u003c\/div\u003e\u003cbr\u003eAll product and company names are trademarks™ or registered® trademarks of their respective holders.
