can then be converted into a known concentration. CMOS sensors are considered to be robust, lightweight and long lasting2. For general IAQ, some manufacturers employ CMOS sensors for monitoring total volatile organic compounds (TVOCs), carbon monoxide (CO), and in some

The RSM741 is a metal oxide semiconductor type sensor in which a sensor layer and a heater layer are formed on an alumina substrate. It can detect the methane (CH4) gas In the sensor, the sensing materials are placed on the alumina substrate , and the resistance of the sensing material is varied according to the concentration of the methane (CH4) gas The RSM741 is fabricated on the TO5 ...

The basic principle behind the SGX metal oxide sensors is that the resistance of the detecting layer in sensor changes in the presence of the target gases. Or in very simple terms, reducing gases remove some of the ‘insulative’ oxygen species at the grain boundaries thus …
