It utilizes a tin dioxide (SnO2) semiconductor material as its sensitive layer. When alcohol vapor is present, it gets absorbed onto the sensor's surface, causing a decrease in the sensor's electrical resistance. The change in resistance is then translated into an analog voltage output, which is proportional to the concentration of alcohol vapor. This sensor is particularly useful in applications where monitoring alcohol levels is important, such as breathalyzers and industrial safety monitoring in environments where alcohol solvents might be present.\u003c\/div\u003e\n\u003ch2 class=\"heading-2 ace-line old-record-id-TVokdmxxuoRO7hxv8rglEnvKgKe\"\u003e\u003cbr\u003e\u003c\/h2\u003e\n\u003ch2 class=\"heading-2 ace-line old-record-id-TVokdmxxuoRO7hxv8rglEnvKgKe\"\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli class=\"ace-line ace-line old-record-id-Mwy5dxOMqo662ExIyJgldTGqgge\"\u003eHigh Sensitivity to Alcohol\u003c\/li\u003e\n\u003cli class=\"ace-line ace-line old-record-id-GMdbdY6EQoCoA6xFntilq4C1gRc\"\u003eFast Response and Recovery\u003c\/li\u003e\n\u003cli class=\"ace-line ace-line old-record-id-KugldNwS6oeLtaxTPLBlFkcZgFf\"\u003eGood Selectivity to Alcohol\u003c\/li\u003e\n\u003cli class=\"ace-line ace-line old-record-id-DBWYd7T9JojF4ex15gAlXJ3Kgwe\"\u003eStable and Long Lifespan\u003c\/li\u003e\n\u003cli class=\"ace-line ace-line old-record-id-GlimdtZDEoA7nFxjUqulIMY6g9f\"\u003eLow Cost\u003c\/li\u003e\n\u003cli class=\"ace-line ace-line old-record-id-HCJDdKZ45okhXkxICFYl8sQagJd\"\u003eSimple Drive Circuit \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 class=\"heading-2 ace-line old-record-id-F3LOdbKkPoNfBoxOVIjlOQKlgLC\"\u003e\n\u003cstrong\u003e\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/h2\u003e\n\u003ch2 class=\"heading-2 ace-line old-record-id-F3LOdbKkPoNfBoxOVIjlOQKlgLC\"\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-TrxBdCeesodqWSxxw0klloOLg4b\"\u003e\n\u003cstrong\u003eTarget Gas:\u003c\/strong\u003e Alcohol Vapor (Ethanol)\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-Q2Igd4vbgoGM7rxnYJ8lbQkUgjd\"\u003e\n\u003cstrong\u003eDetection Concentration Range:\u003c\/strong\u003e 0.05 mg\/L - 10 mg\/L\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-NJ2BdbzNgoZMspx64SnlZ8fUgIg\"\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e 5V ± 0.1V DC\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-SqnXdzh5doiJKExbVxglizSqgMf\"\u003e\n\u003cstrong\u003eHeater Voltage:\u003c\/strong\u003e 5V ± 0.1V AC\/DC\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-NfqWdqW1goJ3RQxYgdcl9NwZgxh\"\u003e\n\u003cstrong\u003eLoad Resistance: \u003c\/strong\u003e200KΩ\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-XXRldBuNsoaBwGxIcmAlownCggb\"\u003e\n\u003cstrong\u003eHeater Resistance:\u003c\/strong\u003e 33Ω ± 5% (Room Temperature)\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-RlxPdnZNMoqLkCxyzgklO4H9goe\"\u003e\n\u003cstrong\u003eHeater Consumption:\u003c\/strong\u003e ≤ 750 mW\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-Kehldmo2kocaX8xkJHFliBKagoE\"\u003e\n\u003cstrong\u003ePreheat Time: \u003c\/strong\u003eOver 24 hours\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-ZvoSdcVVfo4MFixuxfalvZQNgpe\"\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e -10°C - 50°C\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-ENzkdAQmHoCYPKxKYcil32FtgWW\"\u003e\n\u003cstrong\u003eStoring Temperature:\u003c\/strong\u003e -10°C - 50°C\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-PycXdRk1Kofl0gxYF9hlnt7QgYf\"\u003e\n\u003cstrong\u003eOperating Humidity:\u003c\/strong\u003e \u0026lt;
