Features Datasheet pdf HANWEI ELETRONICS CO.,LTD MQ-307A http ://www.hwsensor.com MQ307A CO GAS SENS OR The MQ307A is a tin dioxide semicond uctor gas sensor which has an excellent performance in CO detection. Using a m ini-bead type sensing element with a pe riodic temperature change operation met hod, high sensitivity, selectively, sma ll effect from humidity and other remar kable characteristics have been achieve d. The MQ307A realizes the development of reliable CO detection devices. Stru cture Gas sensitive semiconductor mater ial is a mini bead type and a heater co il and electrode wire are embedded in t he element. The sensing element is inst alled in the metal housing which uses d ouble stainless steel mesh (100mesh) in the path of gas flow. Operating condi tions When the sensor is operated with high/low periodic operation (Fig 2), se nsor signal changes according to the te mperature dependencycharacteristics. By detecting the sensor signal at suffici ent timings (at a high temperature for methane and at a low tem.
