Abstract

The invention discloses a sensor group indoor air monitoring system, and belongs to the field of air monitoring. The indoor air monitoring system comprises a central processing unit, wherein the input end of the central processing unit is electrically connected with a data acquisition unit and a body controller through serial port lines; the input end of the data acquisition unit is electrically connected with a converter; the input end of the converter is electrically connected with the output ends of a carbon monoxide sensor, a formaldehyde sensor, a carbon dioxide sensor, a nitrogen dioxide sensor, a VOC (volatile organic compound) sensor, a temperature sensor and a humidity sensor respectively; and the output end of the central processing unit is electrically connected with a controller, an alarm and a video terminal through serial port lines respectively. The indoor air monitoring system uses multiple sensors to simultaneously detect multiple air data; the air quality is precisely displayed through the video terminal, and a user is reminded of paying attention to pollutant overdischarge in time through the alarm; a mobile terminal can realize remote control and monitoring; and manual calibration can be performed through a calibrator in case of inaccurate sensor measurement, thereby ensuring that the result is more accurate.

Description

technical field [0001] The invention relates to a sensor group indoor air monitoring system, which belongs to the field of air monitoring. Background technique [0002] At present, the air pollution in many cities is relatively serious. People choose to spend more time indoors, and close the windows to prevent the circulation of indoor and outdoor air to isolate the polluted air. Although this method can prevent external pollution from entering the room, it will not last for a long time. Opening windows for ventilation can easily lead to a reduction in indoor oxygen and an increase in 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 maintain su...
