Where is safer on a smoggy day? Three dads try out the PM2.5 detector

It was not until December that we realized that the six words "you can't see your hand in front of you" can not only describe the dark night, but also the smog days in Beijing.

Following the principle of "even if I die, I have to know how I died", I believe that many people want to know the air quality around them and are looking forward to the emergence of a convenient and fast product that can detect the air. Now, the Xiu Xiu PM2.5 detector produced by Three Dads may be able to meet your needs.

Unlike traditional handheld air quality detectors, the Xiuxiu PM2.5 detector has a "donut" shape with a diameter of 6.4CM, which is easy to carry.

The circular button on the top of the machine is surrounded by a breathing light that changes color to indicate the operating status. In addition to the opening on the side for air detection, there is a MicroUSB charging port at the bottom, which means that the Xiu Xiu PM2.5 detector can be moved and work with the help of a built-in battery.

Since the detector itself does not have any display device, the test results need to be presented with the help of a mobile phone APP. After installing this APP called "Sniff" on the mobile phone, connecting the detector to the mobile phone is a magical process. Within a certain range, the mobile phone will automatically search and connect to the nearby turned-on detectors, and display the current PM2.5 test results in the air and information such as device power on the screen. Of course, the bridge between them uses Bluetooth technology between devices.

It is not difficult to see from the search results on the Internet that PM2.5 values ​​below 100 are within a range that is more suitable for human survival. However, considering that the indoor index in "Fog City Beijing" is generally around 150, and the outdoor index can easily reach over 300, and even reach 2000 in the first few days of December, it is simply a joke. I sincerely hope that the relevant departments will be brought to justice.

It is a creative idea to combine the display interface of the test results with mobile phone photography. Although some people initially thought that the purpose of doing so was to guide users to take photos of the detector for connection, we later realized that perhaps sharing environmental photos with PM2.5 detection values ​​is of greater significance. After all, it is very difficult for us in Beijing to find a place with cleaner air.

When it comes to the air environment in public places, the Xiu Xiu APP can be regarded as a practical tool that is worth downloading even if you don't have an air purifier. It is not an application that is simply used with a detector. The air environment ratings of various public places including restaurants and shopping malls listed on the first page of the home screen will undoubtedly greatly enhance the practical value of the APP. Taking the Huayuan Bridge where the Beijing Office is located as an example, people will no longer dare to go to some places such as Subway and Cafe De Coral nearby.

Finally, someone will definitely say, "Detection alone is useless. How do we solve the problem of bad air?" So we must not forget that Three Dads itself is an air purifier manufacturer. With Sniff, you can feel the importance of air purifiers more intuitively.
