I once saw a joke that the air quality is getting worse and worse. The Environmental Protection Bureau said that the car exhaust is the primary source of pollution. Then the netizen commented with a god: the environmental protection label of the car was issued by you, and the oil products were also said to be qualified. Is it my driving posture wrong? There seems nothing wrong with the joke. No matter what the real primary pollution source is, people still have to take precautions against the serious situation of air pollution. The 352 PM2.5 detector is an instrument that can detect the current air PM2.5 content.

The 352 PM2.5 detector is packaged in traditional paper. The front is the rendered image of the 352 PM2.5 detector, and the back is some parameter information of the 352 PM2.5 detector. The manufacturer is Beijing 352 Environmental Protection Technology Co., Ltd. The 352 air purifier has heard a little about it. Does the 352 PM2.5 detector mean that the content of PM2.5 in the air can also be detected by removing two from three?

Open the packaging box of the 352 PM2.5 detector, a machine body and a roll of data cable will give you the first impression that it is a mobile power supply and a power bank.

There are not many things in the packing list. Except for one 352 PM2.5 detector, one data cable, one instruction manual and one certificate of conformity, there is no charger we want.

Take out the device. The 352 PM2.5 detector is shaped like a cube, with an indicator light and logo on the front, rather like a small Bluetooth speaker. The one-piece aluminum alloy fuselage is very textured, which makes its appearance especially high.

The product adopts the laser scattering principle commonly used in the industry. The particle monitoring range is 0.3 μ m-2.5 μ m. The side of the detector is a set of vents, and the only physical keys and USB interfaces are below.

This 352 PM2.5 detector has a built-in battery of 2400mAh. It can be powered on for continuous monitoring for about 14 hours at ordinary times. The performance in terms of endurance is good. It will be more perfect if it is used with 352 air purifier. China 352 will remove haze quickly.

Although the 352 PM2.5 detector does not include a charging head, the charging rating of the 352 PM2.5 detector is 5V/1A, and the ordinary mobile phone charging head can be used. If there is no need for continuous detection, you can also press the power supply for two seconds to shut down, and of course, you can also charge for continuous monitoring.

The 352 PM2.5 detector also has a matching APP. When used together with the APP, the 352 PM2.5 detector can perform data sorting, trend analysis and other functions of long-term monitoring.

First, you need to add a device in the APP to add the 352 PM2.5 detector device to the APP. According to the addition wizard, the user needs to fill in a WiFi password to search for a device.

The device can also be searched quickly, and the 352 PM2.5 detector can be connected by clicking on it. There is no problem that the connection is not smooth as the netizens said. Everything is smooth in the connection process.

The display screen of the 352 PM2.5 detector is made of gorilla 2.5D glass, which is almost the specification of the mobile phone screen. However, the brightness of the LED display is low, and the screen cannot be seen clearly in a slightly strong light. Indoor pollution is 222ug/m ³, which is terrible.

The outdoor test result at night is 251ug/m ³, which is not different from the indoor test, but the value is still high.

The monitoring data can also be synchronously displayed on the APP interface, and the data can be counted. At the same time, the device name, alarm and other aspects can be set in the settings.

The 352 PM2.5 detector's APP can take photos of real-time monitoring data and share them with friends and microblogs. This function is very personalized and practical, which can not only take self photos, but also bask in the air.

In general, the 352 PM2.5 detector is very practical in the current situation of severe air quality problems. With an air purifier, if the 352 PM2.5 detector gives an alarm, it can turn on the air purifier to purify the air, and give your own clean breath of air, giving your family a healthy living space. Some deficiencies are that the LED display of the 352 PM2.5 detector needs to be improved. In addition, the interface, art and functions of the APP need to be strengthened.
