Air pollution has become a serious problem we are facing now, but people are also increasingly aware of the harm of haze. Especially for friends in the imperial capital, the problem of haze is very serious. I remember when I first went to Beijing for internship in early 2012, the smog in Beijing was not as serious as it is now. But now it is necessary to wear masks when going out every day, which shows how serious the haze trend is. It is hard to see blue sky and white clouds when going out, so the smog in some cities is not serious. What if we can know the air pollution index of our environment? So today I will bring you a very practical 352 PM2.5 detector, which can detect the indoor and outdoor air pollution. What kind of performance does it have! (It is also because the express delivery was stopped years ago, which led to the return of products, so the report could not be written for a long time. Here, I would like to express my gratitude to the staff working on the machine and send it again.)

Unpacking

First of all, 353PM2.5 detector adopts rectangular hard paper box design for outer packaging. The simple and elegant white style design is the same as the mobile phone box without the middle PM2.5 detector pattern, both in material and style. Fortunately, the PM2.5 detector is also printed on the side of the box, which is relatively high-end on the whole.

The back of the box is printed with the detailed specifications, parameters, accessories and business information of the product, which is also the consistent style of most products.

The design of the heaven and earth cover is not easy to open the box cover, because there is no notch design. After a lot of efforts, the box was finally opened, and a metal cuboid device and a data cable were introduced. The internal accessories of the box are also extremely simple without a charger, but it is very convenient for most USB charging heads today to charge. However, the output current must be clearly seen to avoid damage to the equipment.

All accessories of 352 PM2.5 detector are as follows: detector host, charging data cable, user manual and product certificate.

Appearance details

Now let's enter today's leading role. The 352 PM2.5 detector is a cuboid full body metal aluminum alloy design. The size is 55 * 55 * 89mm, small and exquisite, and it is very textured in the hand. The four corners are designed with rounded radians without cutting! The built-in 2400mAh large capacity battery also lets us not worry about the endurance. The overall detector is still of great weight, and the author is sure of such workmanship.

There is a logo near the top edge of the front of the 352 PM2.5 detector, and the design of the logo and the work indicator light are ingeniously integrated. When the working indicator is green, it indicates that it is on.

The indicator light is orange when charging, and will turn green after it is fully charged.

On the opposite side are two square openings with large round holes. In fact, one of the two openings is the air inlet and the other is the air outlet. These two ports are the key to detection, so you must be careful not to block them when using them to ensure more accurate detection results. The official also suggests that it is best to place it vertically when using it. Next to the bottom of the air vent is a unique power switch and a micro USB charging port.

After the profile introduction, let's take a look at the bottom. The bottom is very simple. In addition to the printed product parameter QR code and manufacturer information, we can see that there is a ring of hard plastic edge at the bottom so that the metal edge will not directly contact the desktop, ensuring that the desktop will not be scratched. However, if the silicone material is used, it will be better not to slide easily. Maybe the designer also takes other factors into consideration.

The top is designed with a piece of 2.5D glass with round corners, and the screen is covered with a layer of plastic protective film. The edges are very close to each other without any small gaps. Here I have to praise the workmanship of the 352 PM2.5 detector again! When the device is turned on, the screen will display PM2.5 detection value, remaining power, wifi connection, etc. It is enough for air detection, but it would be better if time and voice broadcast functions could be added.

APP function experience

For every intelligent product, APP is indispensable. Scan, download and install the 352APP application to experience the functions. After installation, call 352APP and we can see that first we need to register users, and 352 registration is also more user-friendly. It is convenient for a third party to log in to QQ/WeChat/Weibo. After logging in, click Add Device to connect to the 352 MP2.5 tester.

First, when the tester is turned on, press the power key for 3s to enter the wifi network configuration state. At this time, the wifi icon flashes. Then, on the APP side, according to the wizard, first connect to the home wifi, enter the password, and then search and wait. After the connection is successful, you will escape to the main interface of the PM2.5 detector. The APP interface is very simple and there are few contents!

By clicking the user icon in the upper left corner, a hidden menu will appear on the side, which includes points, user information modification, message center, fault/after-sales and shopping mall. There is no special function. In fact, the main function is to click the column with PM2.5 detector icon on the main interface. You can see some detailed detection data and suggestions, as well as the weather forecast of the city. There are three main function modules at the bottom: linkage, statistics and settings. The linkage function is to start and control with 352 air purifier. The setting function is also very simple. It is used to change the device name, room haze alarm and other settings.

In the statistics function, it must be obvious to all that there is a curve chart for the time, day and week statistics of the detected values, which is very intuitive for users to understand. On the whole, the APP of the 352 detector is a little simplified, and I hope that more functions can be added in the future.

The following are some experience values in different scenarios, and changes can be seen through detection. Compared with the air quality in my hometown, it is relatively gratifying. At least, the blue sky, white clouds and haze are not serious every day. However, if there is no instrument that can detect the surrounding environment, it is still necessary for your own health.

summary

From the experience, we can see that the 352 PM2.5 detector is a very good detector in terms of workmanship, and its compact and delicate body is also very textured. The battery capacity of 2400 Amh is also very powerful, and I think it is a very practical product in real life. It is of great significance for our health. It can let us know the surrounding environment all the time. The detected values are for our reference, so that we can improve the air through other methods, so that we can create a healthy environmental state. On the whole, this PM2.5 detector is worth recommending, but the author believes that the APP still needs to be optimized, enriched and improved. No matter where you are, learn about the air health around you from this moment on. Interested friends can go to the official website to learn about!
