Problems solved by technology

[0003] However, there is currently no complete indoor air monitoring system. The quality of indoor air depends entirely on personal subjective feelings. If you feel that there is a peculiar smell or difficulty breathing, it is too late to turn on the fresh air fan, because the human body can feel it. degree, the indoor environment is already very poor

Embodiment 1

[0035] In this embodiment, the nitrogen dioxide sensor is a side-heating structure, including a ceramic substrate, a sensitive material layer is arranged on the surface of the ceramic substrate, a pair of gold electrodes are arranged on both sides of the sensitive material layer, and a pair of gold electrodes is arranged inside the ceramic substrate. A heating element is provided; the thickness of the gold electrode is 2 mm, and the heating element is a Pt heating wire. The sensitive material is a composite metal oxide, specifically In 2 o 3 A mixture of nanospheres and ZnO nanoflowers with a mass ratio of 30:1. The In 2 o 3 The particle size of the nanosphere is 500nm, which is composed of some small In 2 o 3 The cubes are assembled together, and the surface is loaded with potassium particles, which account for the In of the loaded potassium particles 2 o 3 The weight percentage of nanospheres is 8%. The ZnO nanoflowers are needle-like ZnO flower-like nanostructures w...

Embodiment 2

[0041] Compared with Example 1, the In of loaded potassium particles 2 o 3 The mass ratio of nanospheres and ZnO nanoflowers is 20:1.

Embodiment 3

[0043] Compared with Example 1, the In of loaded potassium particles 2 o 3 In nanospheres, the potassium particles account for the In 2 o 3 The weight percentage of nanospheres is 20%.

Abstract

The invention relates to an indoor air monitoring system with a sensor group. The monitoring system comprises a central processor, wherein the input end of the central processor is electrically connected with a data acquirer and a body controller through a serial port line; the input end of the data acquirer is electrically connected with a converter; the input end of the converter is electricallyconnected with the output ends of a carbonic oxide 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 respectively; the nitrogen dioxide sensor is of a heater-type structure, and a sensitive material thereof is a composite metal oxide which is specifically a potassium granule-loaded In2O3 nanosphere and ZnO nanoflower mixture.

Description

technical field [0001] The invention relates to the technical field of air monitoring, in particular to a sensor group indoor air monitoring system. Background technique [0002] At present, the air pollution in many cities is relatively serious. People choose to do activities indoors more, and close the windows to prevent indoor air circulation to isolate polluted air. Although this method can prevent external pollution from entering the room, it will not be opened for a long time. Ventilation through windows can easily lead to the reduction 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 maintain sufficie...
