An air quality detection device

Abstract

The invention discloses an air quality detecting device. The air quality detecting device comprises a central processing unit, an A / D conversion module, a detecting module and a power module, wherein the power module comprises a mains supply power grid, a solar component, an energy storage module and a selective switch, and the energy storage module and the selective switch are connected with the central processing unit; the detecting module comprises a gas detecting unit, an environment detecting unit, a clock unit and a switch chip, the gas detecting unit is connected with the A / D conversion module and connected with the energy storage module through the switch chip, the environment detecting unit and the clock unit are connected with the switch chip, and the output signals of the environment detecting unit and the clock unit are used for controlling the on or off of the switch chip. The air quality detecting device has the advantages that the effective detection rate of the gas detecting unit can be increased, operation load can be reduced effectively, and the utilization rate of a data storage module can be increased; the air quality detecting device is energy-saving and environmentally friendly and can detect air quality in remote plates without electricity.

Description

technical field [0001] The invention relates to the field of environmental protection detection, in particular to an air quality detection device. Background technique [0002] With the development of the market economy and the improvement of living standards, people have higher and higher requirements for the safety of the family living environment. Air is a necessary condition for people's survival, and its quality directly affects people's health, and indoor air quality has been paid more and more attention. Especially for houses that have just been renovated, most of the decoration materials will more or less release toxic gases such as formaldehyde, which poses a huge threat and damage to people's health. [0003] However, in furniture, paint, and interior decoration, most of the information on the concentration of toxic gases such as formaldehyde is in a "half-covered" state. If ordinary families want to test indoor air quality, they need to hire a third-party testing...

Problems solved by technology

However, this patent has the following deficiencies: 1) the amount of data collected is large and complex, and the requirements for the capacity of the data storage module and the data processing capability of the microcontroller module are high, and the cost is high; A large amount of the same data can be obtained under the same conditions, which not only occupies storage capacity, but also increases the workload for subsequent data analysis; 3) The use of power grid or battery power supply is not conducive to continuous air quality detection in areas without electricity
