It uses \u003c\/span\u003e\u003cspan style=\"line-height: 1.6em;\"\u003eMQ-9 to dectect Carbon Monoxide. The sensor can be used to detect different gases containing CO and combustible gases, it is low cost and suitable for a variety of applications.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv\u003eThe core sensing material of MQ-9 gas sensor is SnO2, which has a lower conductivity in clean air. It makes detection by cycling high and low temperature, and detects CO when low temperature (heated by 1.5V). The sensor’s conductivity is higher along with the gas concentration rising. When temperature rises (heated by 5.0V), it detects Methane, Propane, combustible gas,etc and cleans the other gases adsorbed under low temperature.\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"line-height: 1.42857;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"line-height: 1.42857;\"\u003eThe sensitivity can be adjusted by the potentiometer.
