The formaldehyde gas molecules in the air enter the sensor through the gas-permeable membrane. After oxidation and reduction reactions, electron transfer will result in the positive movement of the electrons, carrying an electric current. This current signal will be amplified and then output. The current size is directly proportional to the formaldehyde content in the air.
In order to eliminate the interference of alcohol, temperature and humidity on the formaldehyde concentration measurement by electrochemical formaldehyde gas sensing technology, Cubic added MEMS processing MOX sensors and temperature and humidity sensors to measure VOC substances and ambient temperature and humidity. At the same time, according to the operating status data of the air purifier and the fresh air system, multi-sensor information fusion is performed to output accurate formaldehyde concentration values.
