This Saturday and Saturday (January 23rd and 24th), I believe that many people are experiencing the rare cold in their memory. Brick experts call it the "overlord" cold wave that has not seen in decades. Today, my friend told me that it snowed in Dongguan... It's snowing... It can be seen that the power and arrogance of the side leak, the author in the north, of course, deeply felt that it was too much to eat. On Saturday and Sunday, he lived at home to avoid the cold. This closed doors and windows, the door is not two doors, not one day at home, what would the air quality be like? Let's have 360 air detection master to answer.

Thank Lei Feng for the trial opportunity!

Product introduction:

360 Air Testing Master 360 Air Testing Master is an intelligent device developed by 360 Company, which mainly detects indoor PM2.5 content. 360 Air Testing Master has adopted industrial laser scattering measurement method, and laser scattering is a more accurate detection method. In addition, 360 air detector adopts sensors with high consistency and good quality. It is equipped with an independent air duct to remove interference links, so that the sensor can directly detect indoor air. It really solved the problem of detecting indoor air rather than "detector" internal air.

▲ The white paper box package has no additional words on the front except for the green 360 air detection master, and simple product information, bar code, QR code and SN information on the back. The mobile phone APP can be installed by scanning the QR code.

▲ The square and upright small box, with rounded corners, is made of engineering plastic. The front is white with black mirror design. The black circle in the middle is the display screen, and the black accessory box beside is equipped with data lines and chargers.

▲ The frame with log color and wood grain processing is elegant and natural, which improves the product's appearance. For the convenience of detection, a large number of air inlets are densely arranged around.

▲ The bottom is a rubber anti-skid base, which is marked with product information and some function diagrams, and the details are handled in place.

▲ The white dot on the top is a function key, which can perform active detection (double click the key), and switch between the numerical display interface and the time display interface (click).

▲ The back design is simple, and the left side is the reset button and USB power interface. Press and hold the reset button for 3 seconds to clear the WI-FI settings and reconfigure networking.

▲ The overall accessories are relatively simple. One 360 air detection master host, one manual or warranty card, one charger and one data cable. The data line is long and convenient for different environments.

Note: 360 air detection master can only be powered on, so please prepare mobile power supply for outdoor use.

Actual experience:

360 Air Detection Master has two working modes: offline and online. Online can be used with 360 Air Guard App on smart phones to detect the air quality of the environment; It can also be used offline without connecting to the APP.

APP download: Scan the QR code or search the "360 Air Guard" through the major application markets to download and install.

Network operation : Press the reset button for more than 3 seconds with a slender object such as a pin and toothpick, and operate according to the screen prompts.

If there is no configuration within the 90S startup or the networking fails, the device will enter the offline mode for detection and display, and the data under offline work will be automatically saved in the device, After the next successful networking, it will be uploaded to the cloud and displayed in the historical data of APP and other clients.

▲ The numerical display interface can display PM2.5 values, temperature, humidity, and networking status information (WIFI icon in the upper left corner). The color of the font indicates the air quality, and green indicates good; Yellow indicates slight pollution be exhausted ; Red indicates serious pollution is exhausted.

▲ In the testing interface, double click the top function key, the instrument will automatically perform active testing, and will be displayed on the screen after testing. Actual feeling, can I can feel the vibration and noise of the fan exhaust. The noise is controlled very little. It is basically silent and acceptable.

▲ The time display interface is white. In addition to the time, it can also display the date and week. At this moment, the air detection master can change the clock from second to second. It's also good to make a clock.

PM2.5 of my home:

Listen, the north wind is rustling outside. Look, it's freezing outside the window. Enjoy, and the interior is warm as spring.

It's really a failure. It's never been so cold in winter for many years. When I saw the screenshots of Inner Mongolia children's boots in - 47 ℃ weather, I felt much warmer.

Test time: January 24, 2016, place: Qingdao, Shandong Province, the temperature of the day: - 8 ℃ - 17 ℃, north wind 6-7, sunny.

bedroom:

16: 08, window closed

▲ The measured PM2.5 value is 28, green. Not bad. The air quality is still so good after closing the window for a day. The author is relieved.

▲ The APP on the left shows that the outdoor air quality index is 85, PM2.5 value 50 The air temperature is - 9 ℃, and the northwest wind is 5 degrees. In this case, the air index is not PM2.5, but PM2.5 will certainly affect the air index, which is proportional to each other.

▲ After networking, you can also view "My Home Air" synchronously through APP.

a living room:

16: 15. Window closed

Balcony:

16: 17. Window closed

▲ They are all closed. They haven't opened the window for a day. It's a joke. The north wind is blowing outside. It's 9 degrees below zero. Open the window for excitement.

restroom:

16: 19. Window closed

▲ According to the instruction manual, it is not recommended to use it in places with high humidity and high oil fume pollution, such as toilets and kitchens. The author speculates that the humidity and oil fume may affect the accuracy of the laser sensor.

kitchen:

16: 20. Window closed

▲ After seeing the indoor, the author went to the outdoor test again. Chairman Mao said that practice is the only standard to test the truth. So the author went outdoors...

Outdoor downstairs:

16: 45, outdoor status

▲ No wonder the PM2.5 value is so low, and it was not high outdoors. This is due to the cold wave. The strong wind brought cold, but also dispersed PM2.5. Did you see - 9.1 ℃? In order to wait for this temperature, the author waited downstairs for a full quarter of an hour, and the cold pumping was fast.

Conclusion:

After this round, PM2.5 was really defeated by the "Cold Wave King", and was driven out of nowhere. Don't be happy too early. The day after tomorrow, when it gets warmer, the "Cold Wave King" will leave, and PM2.5 will return to the high point again. Maybe this fresh air will not be seen until a few days later. At the thought of this, the author deeply despises it in his heart, and at the same time quickly takes a few breaths of cold air.

At present, atmospheric environmental pollution has still become a problem that must be paid attention to. Maybe we can not consider ourselves. After all, after all, we have poisoned for so many years, and our bodies have also adapted. But how can children and the next generation have the heart to let them enjoy this "feast" with us? There is another problem that makes the author worried. This air detection master can only detect and display the air pollution index. However, when you see the red values, if you don't have air purifier and other equipment, you can only stare and get angry.

Maybe, this is to urge and remind us not to escape from reality, but to find a way to improve it, so we can't turn a blind eye and ignore it.

Suggestions:

1. If possible, the formaldehyde detection function is added, and the decoration pollution and furniture pollution are also very serious.

2. Can the built-in battery be used? It's not a big problem with such a large box. It's inconvenient to carry a bunch of things outdoors.

3. Provide supporting environmental treatment programs, or provide supporting air purifiers (affordable, cheap, low cost, good effect), or other programs (such as planting green plants, etc.).
