Abstract
A portable air quality tester comprises a portable box body, wherein a detection circuit for detecting air condition is arranged in the box body; the detection circuit comprises a main control chip U and a power supply module; and the main control chip is connected with a PM (particulate matter)2.5 sensor for sensing the concentration of the PM with particle size being less than or equal to 2.5 microns in the atmosphere, a VOC (volatile organic compound) sensor for detecting the VOC, a temperature and humidity sensor for detecting air temperature and humidity and a display part for displaying the detection result of each sensor. The portable air quality tester has the detection functions of detecting PM2.5, VOC and temperature and humidity, stable performance and high portability and is convenient to use.
Description
Technical field
The present invention relates to the improved technology of air quality tester.
Background technology
Raising with quality of life and the development of social economy, people for living environment attention rate also increasingly
High.In daily life, people compare the air quality paying close attention to interior of being lived, and such as humiture, PM2.5 and volatility is organic
Compound（VOC）Deng air regime.In the prior art, this kind of tester is all very professional main equipment, is not easy to
Mobile use.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of portable air quality test easy to use, portable
Instrument.
For above-mentioned technical problem, the present invention realizes in the following ways：
A kind of portable air quality tester, including a portable casing, is provided with detection air regime detection in casing
Circuit, this testing circuit, including main control chip U, power module, is connected with particle diameter in sensing air little on main control chip
In or be equal to the PM2.5 sensor of 2.5 micron particles thing concentration, the VOC sensor of VOC of detection, detection
The Temperature Humidity Sensor of aerial temperature and humidity and the display unit showing each sensor detection results.
Wherein, it is parallel with electric capacity C1, electric capacity C2 between two electrode outputs of described power module.
The present invention has detection PM2.5, VOC, the detection function of humiture, stable performance, and has preferably portable
Property, easy to use.
Brief description
Fig. 1 is embodiment of the present invention circuit theory schematic diagram.
Specific embodiment
For the ease of the understanding of those skilled in the art, former to present configuration below in conjunction with specific embodiment and accompanying drawing
Reason is further described in detail：
As shown in Figure 1, the portable air quality tester small volume that the present embodiment discloses, can carry with and be detected.
Specifically, this portable air mass detecting instrument includes a portable casing, is provided with detection air regime inspection in casing
Slowdown monitoring circuit, this testing circuit, including main control chip U, power module 5, is connected with grain in sensing air on main control chip U
Footpath is less than or equal to the PM2.5 sensor 2 of 2.5 micron particles thing concentration, the VOC sensor of the VOC of detection
3rd, the Temperature Humidity Sensor 4 of detection aerial temperature and humidity and the display unit 1 showing each sensor detection results.Power module adopts
Plug, from electricity network power taking, is parallel with electric capacity C1, electric capacity C2, for ensureing voltage between power module two electrode output
The stability of output.
During work, each sensor by detect every data transfer to main control chip U, main control chip U will process after
Data is shown by display unit 1, and this display unit 1 can be liquid crystal display or charactron.
In the present embodiment, the main control chip U being adopted is STC15F2K60S2 model single-chip microcomputer, and each sensor is
Prior art, therefore not to repeat here.
Above-described embodiment is the present invention preferably implementation, and non-limiting exhaustion, under inventive concept of the present invention, also
Various deformation and replacement can be made, these all deform and replace the protection domain that should belong to appended claims of the invention.
