Multi-parameter air quality collector

Abstract

The invention discloses a multi-parameter air quality collector, which comprises a double-sided circuit board and a shell for fixing the double-sided circuit board, and is characterized in that a sensor device for detecting various air parameters is arranged on the front surface of the double-sided circuit board in a pluggable manner; the sensor device comprises a particulate matter sensor, a CO2sensor, a temperature and humidity sensor, a formaldehyde sensor, a CO sensor and a VOC sensor; analog circuits for converting detection signals into electric signals are arranged in the particulate matter sensor, the CO2 sensor, the temperature and humidity sensor, the formaldehyde sensor, the CO sensor and the VOC sensor; a central processing unit for analyzing and processing electric signals, acommunication device for transmitting data results of the central processing unit to a client and a power supply device are arranged on the back surface of the double-sided circuit board. The whole structure of the device is miniaturized, and a plurality of air quality parameters can be effectively and safely monitored. In addition, the sensors are installed in a pluggable mode, and subsequent maintenance and replacement operation on the sensors is facilitated.

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 the 1980s, various countries have begun to conduct research on indoor air pollution. A large number of experimental data show that indoor air pollution is 2-5 times that of outdoor air pollution. Sources of air pollution mainly include formaldehyde, benzene, toluene contained in new decoration materials and CO, SO2 emitted from automobile exhaust. 2 Etc., long-term exposure or inhalation of these toxic and harmful gases will endanger human health. Whether modern people are working or resting, they need to spend most of their time indoors, so whether the indoor air quality parameters meet the standards is very important for modern people. [0003] Since the toxic and harmful substances in the air are not single, multiple air quality parameters need to be monitored. According to the compo...

Problems solved by technology

However, the devices used to monitor air quality in the prior art mainly monitor a single parameter. If the monitoring of multiple parameters needs to be realized, multiple instruments and multiple lines are required, which will cause the device to occupy a large space and simultaneously , There are many wires, which may cause fire due to overheating of the wires
