Abstract

The invention relates to a highly sensitive indoor air monitoring system. The system comprises a central processing unit. An input end of the central processing unit is electrically connected to a data collector and a main body controller through serial port lines. An input end of the data collector is electrically connected to a converter. An input end of the converter is respectively and electrically connected to output ends of a carbon monoxide sensor, a formaldehyde sensor, a carbon dioxide sensor, a nitrogen dioxide sensor, a VOC sensor, a temperature sensor, a humidity sensor and a biochemical sensor. The carbon dioxide sensor is an NO2 sensor based on graphene and the NO2 sensor is a thick film type sensor. A ceramic substrate is used as a substrate. An interdigital electrode is arranged on the ceramic substrate and is provided with a sensitive film. The sensitive film is a mixture of CuO nanorods and an Al/In2O3/RGO composite material.

Description

technical field [0001] The invention relates to the field of indoor air monitoring, in particular to a highly sensitive indoor air monitoring system. Background technique [0002] In recent years, with the development of the economy, the air pollution in many cities is relatively serious. People tend to move more indoors, and close the windows to prevent indoor and outdoor air circulation to isolate polluted air, although this method can prevent external pollution. Entering the room without opening the windows for a long time will easily lead to the decrease of indoor oxygen and the increase of carbon dioxide. In addition, furniture, walls, etc. will release volatile harmful substances such as formaldehyde. At this time, it is necessary to install a fresh fan indoors. The fresh fan can filter and purify the indoor air to reduce harmful substances. Part of the purified internal air forms an internal circulation, and the other part exchanges with the filtered external air to m...
