[Preface]

When I was young, white objects that could not be seen at a glance were called fog. Now, yellow objects that could not be seen at a glance are called haze.

Pm2.5 is responsible for most of our daily haze weather. Pm2.5 refers to particles with a diameter of less than or equal to 2.5 microns in the atmosphere, sometimes referred to as lung entering particles. Pm2.5 in the atmosphere as a hidden killer endangers our health.

How can we know the pollution situation of the weather every day, and rely on mobile APP to observe the latest weather forecast at any time? But it is also a large area of location coverage, and can not analyze the latest weather pollution around you. I believe we all hope to monitor the weather pollution around us anytime and anywhere.

The author tried a 352 PM2.5 air detector. It was developed by Beijing 352 Environmental Protection Technology Co., Ltd. It must have been accessible to everyone. More experiences are as follows.

[Unpacking]

The packaging of 352 PM2.5 air detector is exquisite, and the fully armed cardboard box plays a very good role in protection. It is mainly white, which also symbolizes the cleanness of the blue sky. The front is printed with the overall detector large display screen, showing linkage status, wireless connection, power and numerical information. It is estimated that when 352ug/m3 is detected, the machine will give an alarm. Run!!!

353 logo and PM2.5 air detector are printed around. The logo is very interesting. A small dot in the middle connects the opening on the right side, which seems to be devouring bacteria. It is slowly approaching around.

Packaging back, some basic product specifications, internal accessories. Customer service hotline and company address.

It is not difficult to guess the portability of the 352PM2.5 air detector from the size of the outer package of the mobile phone box. You'd better open the package and have a look.

Open the package and simplify the interior decoration. Only the body and data line of the air detector can be seen. Compared with the air detectors on the market, it is relatively large.

After the air detector is taken out, the product data sheet and certificate are on the bottom.

This is enough. I look forward to watching the appearance closely.

Appearance

The 352 PM2.5 detector is a cuboid, all aluminum alloy body with simple color matching, fashionable appearance and good hand feel, which is similar to the body specifications of mobile phones.

The product size is 55x55x89mm, 240g. Whether in a pocket or in a bag, you can check the air quality around you anytime, anywhere. It is also easy to put it at home. Remember that winter is not easy to hold in hand, cold...

The whole surface above the 352 PM2.5 detector is the display screen. 2.5D gorilla glass material, pay attention to the frame, this technology is similar to the phone frame.

When the screen lights up, the system will conduct self inspection, and the value will change continuously. After 30 seconds of inactivity, the value will display the current air quality normally. Today is a rare fine weather in Tangshan. The sky is clear. However, the next day after taking the photo, the strongest snowfall in ten years began to fall.

The author found in the outdoor shooting that when the air detector was turned on, the screen display became dark, so that it was difficult to see clearly in strong sunlight. Why don't you increase the display brightness? Since the size of the body and the processing of the large screen frame are the same as that of the mobile phone, it is also good to add an automatic brightness adjustment.

With such a large screen, the content is too little. It is OK to add more content, whether the weather or air concentration is rising or falling.

The front power indicator will automatically turn on the green light after power on. Why not put the power indicator on the logo on the center circle.

On the back of the 352PM2.5 detector, there are orderly arranged square holes. Here are the air outlet and air inlet. After starting up, remove the air through circulating intake air, and conduct sampling analysis to detect the current latest air condition. Very little movement. Below the small hole are the switch key and charging interface.

We can see the surface structure of the back, and the internal structure is the core. The internal detection device uses a laser sensor with more stable performance and high accuracy, so that its measurement range is controlled within 0-9999 μ m, and the particle detection range is controlled within 0.3-2.5 μ m. The 2400mAH large capacity battery is also installed inside, which can be used for up to 15 hours. It seems that the 352PM2.5 detector is not just a talk.

Pay attention to the precautions at the bottom of the product. The power supply rating is 5V/1A, which does not support fast charging of power bank. Of course, the most important thing is the QR code. Scan it to download the app, and use your mobile phone to intelligently manage the 352PM2.5 detector.

[Practical]

Download the app, log in and register, then slide left into the taskbar to view some functions such as user center, fault and after-sales, online mall, etc.

The 352PM2.5 detector only supports WiFi wireless LAN connection. After downloading the app, search, enter the account and password in the LAN, and then go online. The author has been unable to connect during the test. After questioning, he learned that he cannot be too far away from the wireless. If the distance is too far, this column will appear. (It can be used normally when offline)

Click to enter, there will be a warm prompt, the current air quality is poor, please turn on the air purifier. Enter the equipment page, and the current indoor and outdoor air quality is displayed in the middle. Click the camera above to take photos and share them with WeChat friends circle. It is suggested that 352 company set its own friends circle in the app, so that more users can share together.

The above three pages are linkage, statistics and settings, and linkage can connect the purifier. It can also count the real-time, 24-hour and weekly air conditions, and can also enter the setting interface to make some settings.

This is the air quality monitoring in Lunan District, Tangshan, from 7:00 to 8:00 in the morning. The difference is not too big. Serious pollution. The outer ring is better. You can't compete with the best, you can only compete with the worst.

This is the current indoor air quality monitoring, which is monitored by 352PM2.5 detector and mobile phone. It is easier to believe the inspection quality of the 352PM2.5 detector.

Summary

China's 352 haze removal is fast, and its company's purifier can help us improve the air quality around us. The 352 PM2.5 air detector also makes us more concerned about the air quality around us. According to the mobile phone's body specification, its products should be carried with you and mastered at once. Each set has been strictly calibrated by TSI8530, and the data accuracy error is ± 10%. Such precise workmanship is only to make you and me more comfortable.

Advantages: 2.5D gorilla glass, all aluminum alloy integrated body, 2400 mA large capacity battery, long standby time. The principle of laser scattering is very expressive. Connect your mobile phone for intelligent management. Take photos quickly and share the weather with people around you.

Disadvantages: The screen brightness is insufficient under strong light. The large screen displays single content. When wifi is online, the connection time is long.
