Haze, the word two thousand and thirteen The year has become the key word of the year in China. The Chinese people have learned that the heavy fog weather in our life is not just the water drop suspended solids, but also let everyone know PM2.5 The abbreviation for haze in this standard.

Xiao Bian lives in Beijing. Well, you must have seen the word "Beijing". Besides Tiananmen and Zhongnanhai, the words "haze" have also been added. two thousand and thirteen In, Beijing's non haze weather was only five Days ago, everyone was talking about haze, and at the same time, they were also taking precautions to prevent the air purifier from leaving themselves in a healthy space as much as possible in their living and working places.

But even if you buy an air cleaner, how do you know the air quality? For the public, we know that PM2.5 Most of the information is obtained by relevant software, but most of this information is obtained from the test of your base station in this area. Although the difference is not large, it is not easy to understand your environment in real time.

Xiaobian was lucky to get the public test of Lei Feng.com three hundred and sixty Master of Air, let's experience what convenience this master of air detection can bring to the public today.

three hundred and sixty The master of air detection is composed of three hundred and sixty The company carries out design development and centralized monitoring PM2.5 , humidity and temperature, and can be APP The client performs remote queries. three hundred and sixty Airguard continued on the outer package three hundred and sixty The company's packaging is divided into simple and healthy designs on the front, white background and green characters on the back App Product information such as QR code of The slogan of "Health, Start with Indoor Air" shows that this product is aimed at monitoring indoor air quality.

Open the package, you can see three hundred and sixty The shape of the air guard pays attention to the air quality around at any time and anywhere. three hundred and sixty The overall size of the air guard is small, and it looks like an electronic alarm clock on the desktop. It also comes with a charging plug and data cable along with the host computer and instructions.

three hundred and sixty The shape of the screen is simple, the design of the sky is round and the place is square and chamfered, the display screen in the front white panel uses mirror glass, and the LCD screen is two point four Inch TFT LCD screen, round mirror glass bottom printed with three hundred and sixty Of LOGO

Seen from the side, the side is a sandwich structure, with white panel layers at the front and back, and a gap behind the white front panel with imitation wood grain frame in the middle. An air suction hole is designed in this gap.

The top is a white round key, which is also the only physical key of Air Master. The key is almost on the same plane with the top panel. The main function of this key is to switch between related modes

The back is also made of the same white plastic material as the front, three hundred and sixty Of LOGO Located on the upper side. Below are two interfaces, namely Reset Between heavy and Micro-usb The air detection master does not have a built-in battery, and its work must be connected to the power supply to start. It is OK indoors, but it must rely on the mobile power supply for use outdoors. There are monitoring types on the silicone cushion at the bottom.

Usage

After the power supply is connected, the detection master will work automatically, and the user can view the indoor air quality in real time. The default is the control data display interface, including PM2.5 , humidity and temperature display, as shown in the figure below PM2.5 numerical value thirty-nine , temperature twenty-seven point seven Degree 14.6% 。

three hundred and sixty Air detection masters have their own advantages APP Client（ ios Version is not available yet), download it now App After connecting to the test master, you can pair with the mobile phone and connect to the network step by step according to the prompts on the drawing. However, the Xiaomi mobile phone used by Xiaobian has been connected, reset, power off and restarted for many times, and has not been connected. It is known that some friends' Xiaomi mobile phones also have this problem, but I don't know whether it is MIUI The problem is still the Android version, or the old Zhou's response to the old Lei's eyes, and then replaced the eliminated one sony Connect the phone for seconds later.

After connection, you can change the mobile phone through the Xiaomi mobile phone App Log in, then you can App To view the data, I worked in the one I came back weeks later and found that I could not connect again.. The next generation upgrade of reconnection stability needs to be strengthened.

Click the round button on the top to switch to the time display interface, which can only display the electronic alarm clock without voice. The switch function is good, but I think the time interface function is a little weak. Double click the top button to monitor the air quality in real time. When double clicking, pay attention to leaving an air intake for even monitoring of air.

APP And monitoring data

three hundred and sixty The air detection master adopts the laser scattering method, which is simple to say PM2.5 The index detection is better than the beta ray method. The detection master has a built-in air detection module, which converts the absorbed air into data and displays it on the screen through temperature, humidity and air quality sensors.

For data monitoring, we use the space satellite App Let's talk through the interface of App The data you see is based on the comprehensive air quality index measured by the monitoring station in your area AQI , containing PM2.5 ， PM10 , ozone, sulfur dioxide, nitrogen dioxide and nitric oxide APP The air index seen on the air satellite interface is AQI Index, not separate PM2.5 Index.

three hundred and sixty Airguard App It includes four parts, namely, air quality, home air, national ranking, and live complaints.

Among them, we use the first two items most. Air quality except AQI The index also includes the concentration of major pollutants, air forecast and air quality map of six air quality assessments, which can make it easier for users to understand what the largest pollutant is today, arrange future travel plans, etc., and also query the previous air index of the region.

My air interface is also the monitoring master App The above real-time display data mainly includes PM2.5 And PM10 Two types of pollution. The user can click the air quality to see the detailed data report of data monitoring, and analyze the highest and lowest air quality values in the last three days.

So don't compare AQI The index is compared with the indoor air index at the same level.

Regarding indoor and outdoor air quality, Thomas Through the test, the indoor PM2.5 Generally, it is of outdoor air index 60% Left and right. Through the test, this condition is consistent with that in the home when the window is closed PM2.5 With the outdoor PM2.5 The height of. There is a haze meter in the small editor's hand. Through comparison, we can see what the haze meter shows PM2.5 The index is slightly higher, but the gap is within a certain range, and PM2.5 They all exceed the outdoor index, but it is not ruled out that this is for the manufacturer's own benefit. The small editor does not have a third test tool, so we do not evaluate which is more accurate here.

But let me remind you that what the air detection master monitors is PM2.5 , not AQI Therefore, when you observe the data, you need to compare the indoor data with the PM2.5 index contrast.

Here are some data collected in the school. By the way three hundred and sixty To test the master's outdoor viewing ability, one word: too difficult.

scene one : Peking University Library: open space, windows closed, outdoor forty-one , Indoor thirty-two 。

scene two : Chenghuan College: medium-sized open space, windows closed, outdoor forty-five , Indoor twenty-nine 。

scene three : Peking University Computing Center: closed small space, windows closed, outdoor forty-one , Indoor thirty-four 。

Summary: We need three hundred and sixty Master of Air

There is no doubt about the answer. Of course, there is a need. For China, a country with such a large amount of coal in winter, although the haze weather has improved year by year, it is only macro. As you and I, we can do nothing outside except masks, but we have the ability to improve our small area. We can three hundred and sixty Testing masters and App Always pay attention to the air quality in the home, how about the air in the home, and simply watch the test master or App OK.
