preface:

Living in Beijing, I used to watch the weather forecast every day, especially the PM2.5 data. The PM2.5 air detector of 352 is such a small, lightweight and portable instrument specially used to detect PM2.5. Since then, PM2.5 air data has been monitored at any time, and air quality can be seen.

1、 Brand Introduction

Beijing 352 Environmental Protection Technology Co., Ltd., founded in April 2014, is an innovative technology enterprise focusing on healthy breathing and air purification, and developing and selling products independently.

Everything is for the needs of users, and everything is for the health of users. Put aside feelings and hypocrisy, constantly optimize the supply chain, and provide users with useful and high-performance products through Internet channels. X80 air purifier is the first product of the company, (CADR, 750 m3/h; Service life of filter screen: 1 year; The maximum noise is 55 dB), which has been certified by Shanghai Environmental Protection Association and other professional institutions.

352 is the name of the company and the brand of the product. Originating from "three under five, two out of two", the company's operation should be fast and resolutely implemented; At the product level, it should also be able to "quickly remove haze and achieve extreme purification".

2、 Unpacking live shot

The outer package is a rectangular paper box, and the front is the product screen display, marked with 352 words.

On the side of the package are the words of product LOGO and PM2.5 detector.

The bottom of the package is product parameter information, manufacturer, etc.

Open the packing box and find the products and accessories inside.

The standard configuration is as follows: detector host, USB cable, user manual, certificate of conformity.

3、 Detail display

The official product parameters are as follows:

The mainframe of the detector is a light gray metal cube with an integrated aluminum alloy body, which is simple and delicate. Smooth texture, small and portable.

On the front of the detector, the dot on the top of the LOGO position is the power indicator, and the normal operation status is green.

On the back of the detector, there are USB sockets, power switches and air vents in turn.

The display screen is made of Corning Gorilla 2.5D glass with round corners. When not displayed, the screen is black, and the edge is almost invisible.

At the bottom are product information, manufacturing company, consultation telephone, precautions, QR code, etc. The rubber anti slip ring on the side makes the placement more stable.

4、 Practical experience

When using for the first time, charge it first. The indicator light is orange when charging and green when fully charged.

Scan the user manual or the QR code at the bottom of the detector, and follow the prompts to download and install the APP "352 Air".

Click "352 Air" to register or log in through a third party authorization. Add devices as prompted.

According to the instructions, long press the power on key for three seconds, and the WIFI icon on the screen flashes to enter the instrument networking configuration state. After entering the WIFI password, start the search. After successful connection, the tester will be displayed in the device list.

Click the connected PM2.5 detector in the equipment list to see the relevant information data. Area, temperature, PM2.5 concentration, current pollution degree, etc.

In principle, APP data is synchronized with the display data of the detector. But it is slightly slower, mainly because the detector sends data first and then sends it to APP.

When the PM2.5 concentration reaches a certain value, APP will give a warm prompt.

Take the detector outside, and the outdoor air data displayed by APP is basically the same. Compared with PM2.5 of China Weather Network, the data error is small.

The APP starts taking photos to capture the current landscape and make special pictures showing the current air conditions. Pictures can share the circle of friends in real time.

The statistical function of APP can achieve real-time, 24-hour and weekly analysis of changes in PM2.5 data over a period of time as required.

APP has many other functions, such as personal settings, adding new devices, device settings, sharing, etc.

In order to receive the air signal better, the detector is recommended to be placed vertically. The detector is small and exquisite, moving everywhere, and can be matched with various home styles, suitable for multi environment monitoring.

In actual use, the noise of the detector is basically zero, and the running sound of the detector can hardly be heard. The 2400 mA large capacity battery can last about 12 hours, about half a day. Therefore, if it is recommended to plug in the power for indoor use, it can be temporarily cut off for outdoor use.

5、 Summary

352 PM2.5 air detector, aluminum alloy body, high-quality material, small and exquisite, beautiful design. High precision, stable performance, real-time monitoring and sharing of APP, and small accuracy error of detection data. Lightweight and portable, suitable for multi environment detection, and you can see the air quality around you anytime, anywhere.
