When I was young, foggy weather only happened occasionally. At that time, we looked at the weather forecast and only paid attention to the temperature change. In recent years, with the increasingly serious air pollution, there are more and more "foggy" days. The original foggy days are not pure fog, and most of them are dust particles floating in the air after air pollution (PM2.5) This substance is also commonly known as "haze".

Although the haze is invisible, when its concentration is greater than a certain index, it will affect the air quality and visibility. When people inhale this kind of haze, it will deposit in the lungs, causing irreversible consequences. In serious cases, it may even endanger their lives. Therefore, PM 2.5 has become a very sensitive topic today.

Outdoor PM2.5 (2.5 micron particles) can be obtained through the local weather forecast, and indoor air purifiers can also be detected through their own functions. In addition, it is not so easy to detect PM2.5 data of various indoor environments. Today's editor will introduce a small and portable 360 air detection master.

360 Air Detection Master is a product designed by 360 Company and produced by Beijing Wonderland Environmental Technology Co., Ltd., which can detect PM2.5, temperature and humidity. The front of the box is only printed with the green product name in the middle, which is clean and refreshing. In addition to one product related information on the back, the most impressive sentence is that health starts from paying attention to indoor air. The package includes: 360 air detection master, a user manual, a data cable, and a 5V/1A power adapter.

360 Air Testing Master is only 98.2 * 98.2 * 44.5m in size, not large in size. It is a box with rounded corners and square shape. The front panel is made of white plastic, and the circular black panel in the middle is slightly protruding. There is a 2.4 inch TFT LCD in the middle of the black panel, which is integrated with the surrounding black. Because the black front panel is also treated with mirror reflection effect, the small box can not only detect data, but also be used as a small mirror. Unfortunately, the content displayed on the screen can hardly be seen in places with strong sunlight, especially the red font.

A white round button on the top is the only functional button of the machine. Press it once to switch the screen display content from the detected PM2.5 data to the current time; Press again to return to the display of the detected data, and press 2 to perform an independent data detection.

There are five rows of small ventilation holes on both sides of the fuselage. When 360 Air Testing Master works, he takes the initiative to inhale ambient air here for testing. There is a light gray rubber anti-skid pad on the bottom of the fuselage, and there are also some product models, websites and other information on it.

The back of 360 air detection master is also made of white plastic, which may be embedded in a metal drawbar metal plate to make the power interface more durable. Plug the random power connection cable into the Micro USB power interface, and 360 Air Testing Master can start up and test. The small round hole next to it is a reset hole. Holding it for 3 seconds with a pointed object will reset the device so that it can be connected to the APP again after changing the network.

The detected data will be displayed directly. PM2.5 value, humidity and humidity are detected and displayed together. After pressing the top button, the display screen will switch to the time screen, including time, month, day and week. There is also an air quality sign in the upper left corner, and the words "heavy" in red can be seen in the picture.

At present, 360 air detection masters only have Android clients. Scan the QR code on the back of the packaging box or download the Air Guard APP. When the device is powered on, it will prompt "The device is waiting for networking, please open the APP". At this time, open the Air Guard APP and find the+sign in the upper right corner of<My Home Air>to add the device. What should be noted here is that when installing the Air Master APP, the APP should be allowed to locate in the security permission option. If it is closed by default during installation, it should be manually opened, otherwise it will be unable to connect with the device. This is also a small experience that Molly has learned from her own practice.

In addition to urban air quality index, PM2.5 concentration, temperature and humidity detected by hardware equipment, Air Guard APP can also view the national air quality ranking and pollution map. When the screenshot was taken, the PM2.5 in my home air was 80, and the weather forecast environmental pollution index was 145 at that time, of which PM2.5 was 110. It can be seen that the indoor air quality is better than the outdoor air quality. In addition, there are detailed air quality reports, including hourly PM2.5 and PM10 indexes, and the best and worst indexes of home air quality in the last three days.

In the column of "Air Quality", there are local weather conditions, temperature, wind level, air pollution index, and the following is a health guide broadcast by radio, which gives some warm tips for people to fight against pollution. In the column of<National Ranking>, you can view the pollution index rankings of your city and other cities in order or reverse order. The pollution map in the upper right corner can more intuitively view the pollution index of more cities, and use different color marks to show different pollution levels.

Click the upper left corner of the Air Guard APP to view, add and delete the cities to be displayed; You can also see the pictures and testimonials uploaded by netizens in the "Live Complaint". Here, more professional environmental pollution information is concentrated, and more urban environmental information can be learned.

Harbin people spend almost half a year in winter. Because of specific factors such as heating, they also emit more smoke than other seasons. Therefore, besides snow and ice, the most common winter in Harbin is smog. In the days when 360 air detection masters were used, most of the PM2.5 was above 100, and the 16th was the day when the air pollution was the most serious.

Molly put the master of air detection on the windowsill and closed the window so that there would be no indoor gas affecting the collection and detection of outdoor air quality. After about 20 minutes, she refreshed the collected data in the room with her mobile phone during this period. The master of air independently detected once every 2 minutes, PM2.5 is rising, and the temperature and humidity are also changing. When it is taken out of the room, the temperature of 20.7 ℃ drops rapidly to nearly 0 ℃. Then a strange phenomenon occurs on the APP side of the mobile phone. After the air box device is below zero, the temperature on the APP side shows more than 6000 ℃, which should be a bug.

Even if 360 Air Master does not connect to the Air Guard APP, it can also realize the function of detecting data and screen display. When it is connected to the mobile phone next time, the current data detected will be automatically transferred to the Air Master APP.

advantage:

• Lightweight, easy to carry to different environments for measurement;

• The fan has a low voice.

• Wooden texture, beautiful appearance;

Disadvantages:

• There is no built-in battery, so it should be placed at the place connected to the power supply or used with the mobile power supply.

• If there is no switch, the device can be switched on when plugged in. If there is a switch, it is more convenient to control.

• The mirror design of the display screen seriously affects the brightness of the display screen.

• The air guard APP displays an error when the temperature is below 0 ℃.

360 Air Testing Master can be regarded as a master of exquisite workmanship. The imitation wood texture is better matched with the home. It can improve the beauty of the environment wherever it is placed. It can also be used as a clock and mirror at ordinary times. The small figure can be placed freely. If the built-in lithium battery is added, its ease of use will be greatly improved when it is used, especially outdoors. The self inhalation design is currently tested every 2 minutes. It is recommended to increase the custom test time so that the fan's voice will be smaller. PM2.5， Although the fine particles in the air are colorless and tasteless, they are easy to be ignored, but they really exist. Every family should master the air quality and health of the living environment, starting from paying attention to the indoor air.
