Write in front

Under the same sky, haze is now the focus of everyone's attention, and air purifiers are gradually becoming a member of smart homes. The air purifier has its own air quality detection function, but it can be used only when it is running. With the air quality detector, it can detect the air quality in the room in real time, and turn on the air purifier to purify the air when necessary. Next, Xiao Feng will talk with you about the PM2.5 detector launched by 352 Environmental Protection Technology Co., Ltd.

Unpacking process

The front of the white mixing box is the product display screen pattern, the side is the product name "PM2.5 detector" and the product logo, and the top of the bottom is the product label, with detailed accessory information and product parameters inside.

Remove the box cover. Inside is the 352 PM2.5 detector in bright metal color, and place it on the base with the power cord neatly.

The 352 has a cuboid shape. The four sides of the 352 have an integrated aluminum alloy metal shell with frosting process. It has a better feel. Below the LED work indicator hole on the front is the product logo with metal etching process.

There are two symmetrical mesh openings on the back of the 352, which are used for air circulation detection. The lower part is equipped with a power key and Mirco USB power interface. The built-in battery capacity is 2400mAh.

The top is the 2.5D gorilla glass display screen popular in mobile phones. The whole section is square with arc edges. The transition between glass and metal is natural. The whole product gives people the visual effect of handicrafts. If it is used as a family decoration, it is also good.

At the bottom are the simple parameters, precautions, MAC address and QR code of the public number of the product. The 352 supports DC5.0V/1.0A power input. It has passed the EU RoHS certification and can be used with confidence.

There are 1 meter USB data cable, user manual, product certificate and other accessories in the packaging box. The data cable is stored in a transparent plastic ring, which looks more thoughtful than those who use cable ties.

Compared with other air magic boxes, 352 is more beautiful in appearance and smaller in size.

Practical experience

It can be seen from the packaging box that the 352 detection resolution is 1ug/m3, and the particle detection range is 0.3~2.5um. The laser scattering principle is used for detection, with more stable performance and more accurate data. 352 can be used directly. Press and hold the power key for 1 second to start the machine and automatically enter the detection. After a few seconds, the current air quality will be displayed. The power indicator light is green during operation. After 5 minutes of no operation of the key, the machine will automatically enter the background operation mode, and the screen will turn off to achieve power saving effect.

When used with 352APP, the air quality data detected by 352 can be viewed in real time. According to the instructions in the user manual, scan the code to download and install the app, enter the device list page after logging in the account, set up the wifi network to be connected, press and hold the power button for 3 seconds to enter the pairing state, and then automatically search for the device to complete the binding after 10 seconds.

After adding 352, it is displayed in the PM2.5 detector category in the equipment list interface. The air purifier category can only be added with its own products, and cannot be added with other brands. Click the button in the upper left corner to call up the system menu bar, which provides the integration center, user center, information center, fault and after-sales, access to the mall, about, etc.: in the user center, you can set your nickname, gender, occupation and avatar, and the address is automatically obtained according to GPS positioning; The message center can choose whether to push messages to the mobile phone, provided that the app resides in the background.

At 352, the equipment enters the main interface, where the indoor and outdoor air quality is displayed with circles. If the air quality is good or below, the software will remind the user to turn on the air purifier. The setting interface at the lower right corner provides the modification of equipment name, selection of room name, haze alarm switch and threshold setting, region selection, etc. The linkage device at the lower left corner is the setting that automatically starts the 352 home purifier when the air quality is poor. PM2.5 statistics provides ug/m3 change curves in real-time, 24:00 and Wednesday forms, so that users can intuitively understand the changes of indoor and outdoor PM2.5. Light mosquito repellent incense next to 352. The 352 sensor sensitively detects the change of air quality, and the PM2.5 value rises to 405ug/m3, indicating that the detection effect is good.

Thanks to the built-in 2400mAh battery, the 352 has an actual life of 15 hours under normal conditions, which is convenient for mobile users. USB voltage and current meter is used for charging statistics. The cumulative input power is 2813mAh. Considering the charging loss, it is consistent with the nominal battery capacity. If it is used in a fixed room, connect the power supply.

Experience summary

The 352 PM2.5 detector skillfully integrates 2.5D glass and metal, adopts the detection principle of laser scattering, judges the change of air quality in a timely manner, and provides a detailed change curve. In this haze era, it is a good PM2.5 detector.
