Multi-parameter air-quality acquisition unit

Abstract

The invention discloses a multi-parameter air-quality acquisition unit and relates to the technical field of air-quality monitoring. The multi-parameter air-quality acquisition unit comprises a surface cover, a bottom shell, an air-duct baffle plate, a circuit board, a CO2 sensor, a TVOC (Total Volatile Organic Compound) sensor, a PM2.5 sensor, a temperature-humidity sensor and a fan, wherein thebottom shell and the surface cover arranged above the bottom shell form a shell of the acquisition unit; the circuit board is arranged on the bottom shell; the air-duct baffle plate is arranged at themiddle part of the circuit board; the circuit board at one side of the air-duct baffle plate is provided with the CO2 sensor, the TVOC sensor, the PM2.5 sensor, the temperature-humidity sensor and the fan, and the circuit board at the other side of the air-duct baffle plate is provided with a communication module; the circuit board is provided with a wire-incoming groove hole; the side surface ofthe shell consisting of the surface cover and the bottom shell is provided with an air outlet, an air inlet, a network-line passing groove and a power-line passing groove. The multi-parameter air-quality acquisition unit disclosed by the invention has the advantages that online real-time monitoring of five air-quality parameters is realized, so that the cost of data acquisition is reduced, and the reliability of air-quality acquisition is improved.

Description

technical field [0001] The invention relates to the technical field of air quality monitoring, in particular to a multi-parameter air quality collector. Background technique [0002] Since indoor air quality monitoring includes multiple parameters, not a single parameter can reflect the quality of indoor air quality. According to the composition of pollutants, the monitoring parameters usually include the concentration of carbon dioxide in the air, the content of fine particles, and the total amount of various harmful gases. The concentration of volatile organic compounds, as well as the temperature and relative humidity of the air, while the traditional air generally adopts a single-parameter monitoring mode. To realize the real-time monitoring of all the above-mentioned air indicators, it is necessary to increase the workload and channels of on-site wiring, so that not only The cost of data collection is greatly increased, and the reliability of air quality collection is d...

The concentration of volatile organic compounds, as well as the temperature and relative humidity of the air, while the traditional air generally adopts a single-parameter monitoring mode. To realize the real-time monitoring of all the above-mentioned air indicators, it is necessary to increase the workload and channels of on-site wiring, so that not only The cost of data collection is greatly increased, and the reliability of air quality collection is difficult to guarantee. Based on this, it is still necessary to design a new type of multi-parameter air quality collector
