Introduction

Today, with the rapid development of electronic technology, intelligent devices, as a life aid tool, are widely used in people's homes; Whether it is large to intelligent cinema system or small to inconspicuous smart socket, they can bring great convenience to our life. I believe that every friend's home will have one or several small devices to measure room humidity and temperature, or use an air purifier to detect PM2.5 index, temperature and humidity; In particular, families with small babies should be equipped with these devices to create a warm and comfortable environment for the growth of babies. According to the readings on these devices, parents can understand the current temperature and humidity in the room, and then turn on the air conditioner, humidifier, purifier and other electrical appliances for adjustment.

The 360 air detection master presented to you today is an intelligent home product created by Beijing Wonderland Environmental Technology Co., Ltd. based on the concept of convenient user control, intelligent detection, etc. This product is different from the traditional air detection product in appearance. It is better integrated into the smart home style by using plastic frames with wood like effect. In terms of performance, it can not only detect the temperature and humidity in the room, but also measure the PM2.5 index with the high-sensitivity sensor inside, and query the detailed report of air quality in the home according to the mobile phone APP, so as to create a healthy and comfortable home environment for users. Next, let's start this evaluation journey together with our editor.

Open box display

three hundred and sixty The air detection master uses white gift box packaging, and only the product name is marked on the front of the box, which is very simple; On the back is a brief description of the product model and testing items. The most impressive sentence is "health, starting from focusing on indoor air", highlighting the theme of the product.

The way to open the packaging box is still a common problem of this kind of smart product packaging. Because of the air resistance and no place to start, it is not easy to open it; Xiao Bian suggested that two semicircular grooves should be designed on both sides of the box to facilitate users to open the package. 360 Testing Master uses thick sponge pads around the host to effectively prevent product damage caused by collision during transportation; The accessories inside are placed in a separated layout, which not only maximizes the use of space resources but also makes them more uniform in visual effects.

In addition to the box itself, the accessories part also includes a power adapter, a standard USB data cable and a manual. It is worth mentioning that the rated output parameter of the power adapter is 5V/1A, which can be easily replaced as the chargers of mobile phones and tablet electronic products we usually use.

The user manual gives a detailed description of the product's functions, operation steps, precautions for use, and relevant parameters. The editor recommends that you read it carefully before use to avoid misoperation during product testing.

The front, back and side of the product are displayed, and the shell is made of plastic technology material with wood like effect, The appearance looks beautiful and fresh, very delicate and full of science and technology, With a square fuselage and smaller overall dimensions, It is very convenient to carry and change places of use, and can be well integrated into the home environment as a table art even when not in use on weekdays. In order to better understand the product performance before use, the parameters are summarized as follows.

Detail display

There are 360 product logos under the display screen of the air detector and on the back of the body. As a well-known company, 360 has a good reputation in the fields of routers, children's watches, mobile phones and other products; It is believed that the smart home product featured by 360 Air Testing Master will not disappoint users.

There is a gray signboard at the bottom of the machine, on which the icons of detection functions and power parameters and other information are marked; It is also a anti-skid rubber pad with high friction coefficient, The machine can be stably placed in any desktop, tea table, bedside table and other environments, without fear of sliding and toppling.

There is a white physical button on the top of the fuselage, through which the machine can be easily operated and controlled; The single machine button switches the display content of the display screen, from the measured data to the current time and date display; Click the button twice consecutively to conduct a real-time data monitoring, and the value will appear on the display screen after completion. The operation is so simple.

There are many ventilation holes densely distributed on the side of the fuselage A small motor is built in the testing master. During the testing process, the motor works to draw the surrounding air flow through these air intakes into the body, and the sensors of various functions begin to detect; The air inlet must not be blocked by air dust or impurities, otherwise the measurement results will be seriously affected. Therefore, the small editor also suggested adding some measures such as dust-proof nets.

The back of the machine is made of plastic material, and the USB charging interface and RESET button are designed on the bottom strip shaped metal wire drawing panel. The interface layout is reasonable, and the appearance effect is good. The drawback is that the air detection master does not have a built-in lithium battery design. When using it, you need to always connect the power adapter or mobile power supply, which greatly reduces the user's experience.

The round display area is equipped with a 2.4 inch true color TFT LCD screen, which supports three font colors of green, yellow and red, respectively representing good air quality, light pollution and serious pollution warning information. However, during the actual experience, the editor found that the display screen was used in the dark indoor environment, and the reading was still very clear; However, when it comes to outdoor detection, the values on the screen seem to be blurred a lot.

The imitation wooden plastic shell around the fuselage is a highlight, which adds some classical artistic beauty to its scientific and technological level, which is very attractive. Arc chamfer structure is adopted at the side of the fuselage and the four corners, which is more beautiful and also increases the safety factor. When carried directly by hand, it can prevent stabbing the hands.

Disassembly analysis

It is clearly mentioned in the instruction manual that it is forbidden to disassemble the machine without permission, otherwise the measurement and use will be seriously affected. However, Xiao Bian is a DIY expert. In addition to the nature of his work, how can he resist not taking apart to understand the internal working principle? However, during the disassembly process, it should be noted that impurities, particles and other dirt should not be mixed into the machine.

Unscrew the two screws at the bottom of the machine, and gently open the back cover to see the circuit board inside. I think the space inside is still large, and it can fully accommodate an extra lithium battery of several hundred milliamperes. I wonder why the manufacturer didn't design it?

Unscrew the four fixing screws on the circuit board and disconnect the wiring of the display screen and the back cover at the same time to separate the circuit board. There are air acquisition module, WiFi module, intelligent IC chip and various electronic components such as capacitors and crystal oscillators. Careful friends must have found a reserved "formaldehyde" module position on the circuit board. At first, it was quite different. Why didn't you add this function to air quality monitoring? It seems that the product is still in the improvement and testing stage, and I believe that this function will be added later.

Because Xiaobian is engaged in equipment research and development in Japanese enterprises, and is familiar with sensors and electronic components, here we also briefly introduce the working principle of the product. The environment detection master has built-in sensor chips, temperature and humidity sensors, gas sensors, PM sensors, etc. When the air intake vents draw the surrounding air flow into the body, each sensor will convert the corresponding signal into a level signal, which will be converted into a digital signal through the calculation of the IC chip on the PCB circuit board and then converted to the mobile phone APP for synchronous display through the display screen and WiFi module.

The back of the circuit board shows that the hardness and internal wiring of the whole board can show that both the quality and the integration of components are relatively high, and the solder joints of each component are also very good.

On the front panel is the TFT LCD display. There is nothing special to explain. The editor will not continue to disassemble it. The small black area on the left edge is the air inlet area, which is not as large as the row of air inlets seen from the outside.

Use test

For the use method of 360 environment detection master, you can start to operate after reading the manual. The display screen displays the current time, date and other information through white font.

Single machine/double click the top button to switch the measurement time interface and update the measured air quality in real time. It should be noted that the machine should be kept in a stable state as far as possible during the measurement, otherwise the measurement results will be affected due to the uneven absorption of air.

Keke, first of all, I live in Tianjin, which is also a city that has been shrouded in smog for a long time. The PM2.5 value shown in is the real test result in the university library. Students drink coffee and read books every day in this environment. Maybe many people do not know how the air quality of their environment is.

According to the test results at the school gate in the evening, PM2.5 is about 261, and the real-time data released by the website on that day is about 245. It seems that the accuracy of 360 environmental detection masters is relatively reliable.

After a night of cold wind, the air quality of the next day was relatively much better. The editor tested at the school gate, the teaching area and the library. The PM2.5 value was about 50-100. The official PM2.5 result published on the website that day was 84. Here you can also go outdoors and the words on the display screen really look hard.

APP use

three hundred and sixty The air detection master can use the mobile APP synchronously, and can understand the air quality in the home more comprehensively. Search through the app store or scan the QR code connection to download the Air Guard software application for installation. After installation, you can quickly log in according to the third party account such as QQ, and you can see the real-time air quality of the current city and the detailed values of various pollutants such as PM2.5 on the home page of the software.

APP The connection with the inspection master is also quite easy. Add the machine by pressing the+button on the upper right corner of the motor. After selecting the product type, press and hold the reset button on the back of the machine for about 3 seconds. After waiting for the networking prompt, complete the connection step by step according to the mobile phone prompt.

After successful connection, the software APP will automatically synchronously detect the values on the screen displayed by the master. Click the outdoor air quality below to view the current urban PM2.5, nitrogen dioxide and sulfur dioxide values; The software can generate a detailed report on air quality, make statistics on the air quality in the home for several consecutive days, and give users an intuitive comparison.

In the setting options, you can add geographical location information, detection master information, system upgrade and other related operations.

In the national air quality ranking list, you can find yourself sitting in the urban air index ranking, and you can also complain about the haze weather. Taking pictures of street scenes with cameras and sharing them with friends all over the country is equivalent to a social forum.

Users can also set software notification alerts, haze pollution alerts, and query common problems, and operate according to their actual needs.

summary

As for this 360 Air Testing Master's evaluation post, I have brought so many things to you. There may be some things in the article that are not detailed or comprehensive. Please comment and correct them. In general, this product has killed many similar products in the market because of its beautiful appearance and practical performance; However, during the evaluation process, Xiaobian also found several shortcomings of the product, which are summarized as follows. I hope the manufacturer can consider the suggestions of Xiaobian.

1、 It is recommended to add a built-in lithium battery to enable users to get rid of the shackles of external power supply and use it more conveniently.

2、 three hundred and sixty It is difficult to see the displayed values clearly on the display screen of the air detection master outdoors. I hope that the reading color or display brightness can be improved.

3、 The product only has a separate detection function. If the relay socket can be added, when the air quality in the home is poor or the temperature and humidity are abnormal, the air conditioner, air purifier and other equipment will be automatically connected for automatic adjustment, making it more intelligent.

4、 It is recommended to add a voice broadcast module to enable users to interact with the product, or support the voice direct departure detection function.

5、 It is hoped to add modules for detecting formaldehyde pollution and noise pollution in the air to enrich the functions of the product.

6. The outer packing box of the product needs further improvement. The current opening method is laborious and inconvenient to use.
