Semiconductor materials was laid on the base, and the corresponding electrode was lead to. the semiconductor material has selective adsorption to the gas that changes the electronic concentration which also raises hall coefficient, corresponding changes the export of hall electromotive force, so the gas sensors which is based on hall effect was made
當我們把半導體材料塗敷到基片上，並引出相應的電極，由於氣敏材料對個別氣體有選擇的吸附特性從而改變了材料中的電子濃度，也就引起了霍耳系數的相應變化，輸出的霍耳電動勢也跟著變化，就製成了基於霍耳效應的氣敏傳感器。 -
In the hall effect, hall electromotive force is not only related to the current density, magnetic field and the distance of the poles, but also to hall coefficient directly
據知，霍耳效應中輸出的霍耳電動勢除了跟輸入的電流強度、磁場強度及輸出電極的間距有關外，還與霍耳系數成正比。 -
The semiconductor material has selective adsorption to the gas that changes the electronic concentration which also raises hail coefficient corresponding changes in the export of hall electromotive force
這種新型傳感器不僅可以根據需要輸出幾毫伏至幾十毫伏甚至幾百毫伏的直流電壓，而且具有其它半導體傳感器所沒有的優點無需另外加熱。
