preface

The annual Spring Festival holiday has passed, but the environmental pollution caused by fireworks has always been a problem we enjoy talking about. Even the crosstalk after zero at this year's Spring Festival Gala also extended to this problem. Fireworks and firecrackers will not only make the sulfur dioxide, carbon monoxide, nitrogen dioxide, sulfur dioxide and inhalable particles in the air exceed the national standards. It will also cause great noise pollution. Today, let's use a 360 air detection master to analyze PM2.5 on New Year's Eve. Before the analysis, we should have a certain understanding of this product.

Unpacking and appearance

The packaging of goods is a popular hard box packaging, with relatively strong protection. The product logo of 360 Air Testing Master is printed on the front. It gives people a very fresh feeling.

The back of the outer package is labeled to briefly introduce the parameters of the product and provide the QR code for downloading the product APP.

360 Air Testing Master has adopted a square round design with a size of 98.2 * 98.2 * 44.5mm, which is slightly larger as a single equipment used for testing.

There are two air collection ports on the side of the product to collect PM2.5 in the air.

360 Air Master has only one physical button, and the button is used to switch the display content.

USB power supply interface and system reset button are set on the back of the product.

Anti slip mat is set at the bottom.

Disassembly

There are two screws in the anti slip pad. After unscrewing, we can open the back cover of the product.

After unplugging the rear power input cable, we can remove the rear cover. After unscrewing the fixing screws on the four corners. After unplugging the display power cable on the front of the circuit board, we can take out the main circuit board.

We can clearly see that the circuit board has reserved enough space for subsequent formaldehyde detection.

positive:

back

I won't dismantle the display screen.

There is a place above the capacitor on the circuit board where liquid leakage is felt.

The air collection port on the left side of the product is used for PM2.5 detection, and the one on the right side should also be reserved for formaldehyde detection.

360 Air Testing Master must connect through APP when using it for the first time. Now let's take a look at the Air Guard app.

APP Introduction

After opening the APP, first connect it according to the instructions.

APP is mainly divided into four interfaces.

Air weight: used to display the overall air quality of the current region. You can also see a lot of weather and air quality related information by clicking and pulling down.

Home air: used to show the current environment of 360 Air Masters. You can also check the change of air in your home

National ranking and live complaining: If you have any dissatisfaction, just spit it out. After reading this ranking, I found that I still live in a better place.

After so many introductions, the main function of this product has not yet been reflected. Now let's enter the measurement link. Let us know what kind of environment we live in.

Measured

The first thing to test is your own office. One third of the time in a day is spent here. After a survey, the environment is OK.

I went to the Personnel Department to have a look. The girls there never smoke. Alas, the air quality is better than ours

Finally, I came to the office of those smokers and went there. It was suicide.

Now let's enter into the highlight of this test, how much the fireworks and firecrackers on New Year's Eve affect PM2.5.

18: 04: At this time, everyone is preparing for dinner. The firecrackers for dinner are starting to set off, and the air quality is passable

17: 04: Finally, PM2.5 produced by fireworks and firecrackers began to spread in the air.

20: 02: The air was filled with smoke. It's horrible.

At 21:12, PM2.5 finally began to fall back, and there were sporadic firecrackers in the distance.

22:07: PM2.5 rose 100 points in four hours. The round of firecrackers at 6 o'clock had such a big impact.

23:07: Finally, I saw PM2.5 fall back, but the next round of super explosion is coming

00:04: Firecrackers are blaring outside. I woke my daughter up. Ah. I am so surprised. PM2.5 is rising continuously.

01:00: My baby can't eat anymore. He fell asleep. Haha, but according to the situation just now, the PM2.5 is definitely more than 300+.

Product suggestions and summary

360 Air Master can be said to be a sensitive product used by Xiao Bian to detect the air quality. Although we can not accurately know whether the detected data is very accurate, the data response after clicking a cigarette is still clear and fast in actual use.

At present, this product still has many shortcomings: First, the screen glass surface is very reflective, and when the value reaches the red value, it cannot be seen clearly in the sun. 2、 At present, the common problem of portable air detection devices is that they cannot carry built-in batteries. 3、 The maximum value can only reach 500 during detection, and a cigarette will directly explode the meter in the past.

With the emergence of environmental problems, people pay more and more attention to air quality. Various air purifiers have sprung up like mushrooms. More than N families began to buy purification equipment for their own health. However, if this goes on, everyone only cares about their own small home. Can we go out in the future? For the sake of our future generations, care about the general environment of our life.
