I have always been concerned about environmental issues. Since I learned about PM2.5, I have continued to pay attention to it. As I was in a third tier town, I always felt that the pollution might not be as serious as that in the capital. When the city announced PM2.5, I knew that it was not that the pollution was small here, but I did not know that the official data of the city was 100+at each monitoring point for a long time, and it would be less than 100 only after rain, According to American standards, it is polluted for a long time. Alas, helpless, how can we protect our own pure land under the dome? We cannot change the big environment, but we can create a small pure land for ourselves. To solve problems, we must first understand the problems, so we need to understand the environmental problems around us. The 720 Environment Treasure allows us to test the air quality around us.

Appearance

The packaging design is very good. Health is my best gift.

If I didn't tell you it was an air detector, I would think it was a power bank (originally, it also has the functions of a power bank, with a 3600 mA lithium battery, which can be used as a temporary single power bank). A USB interface, a Micro USB interface, and a switch button can be seen on the side when the power bank is used.

Noise monitoring microphone, Bluetooth indicator, PM indicator, formaldehyde indicator and noise indicator on the top. The indicator light doesn't feel obvious.

The bottom serial number, and the air detection port (need to lie down during detection), and precautions.

In general, it is small in appearance and weighs only 175g. It is very convenient to carry, and it will not be burdensome to put it in your purse. The appearance is standard, not particularly eye-catching, the side seam is too large.

Use

When using Environment Treasure for the first time, you need to charge it, then scan the QR code on the manual to download the Environment Treasure APP, pair according to the prompts, and use it after pairing.

Comprehensive test, and formaldehyde test. Comprehensive test can test temperature, humidity, noise, PM (official reply is PM2.5), and formaldehyde.

The comprehensive test results suggest that humidity, noise, PM， And formaldehyde, and I will enter the corresponding mall to prompt you to buy the corresponding products.

The value of the test result corresponds to the level.

Settings tab, and historical test data.

Summary

The packaging design is good, the appearance design is defective, relatively ordinary, the quality control is not good enough, the seam is too large, and the indicator light is not obvious. On the appearance, it is hoped that there can be a display, which can display indoor temperature, humidity and timing when not testing at ordinary times, or manually test PM2.5 display, or display P2.5 data of local outdoor monitoring points. It has good portability and can be easily carried to test air quality in different occasions. For example, when I went to eat hotpot, I tested it.

In terms of functions and apps, the noise test function is not accurate, and I feel very quiet. The test results show that the noise is very loud, which should be caused by the test noise of this machine. PM and formaldehyde tests are relatively accurate. The app design is simple to use, but I don't like the environment mall. It gives a feeling of unprofessional. Since it is a professional testing device, I want professional testing data and suggestions, not simple suggestions. It is a prompt to click to buy something. The advertising is too strong. In the discovery column, there are news and mother and baby columns, and there are hints to download mother and baby apps. I really don't like the mother and baby columns in the environment mall and the discovery column.

On the whole, Environment Treasure is well behaved, portable, and has expanded the functions of Power Bank. I just hope that the appearance and details of the app can be improved, as well as the sharing of the app. I hope that the manufacturer can provide an incentive mechanism, otherwise the sharing is really useless, and the user stickiness is not enough. I got the product and tested it several times in various rooms at home, once by the company, and once by the restaurant. Otherwise, people will only use it as a power bank. Of course, thanks to the Environment Treasure, which let me know that PM2.5 pollution in my home is so serious, so I decided to decorate my new house directly to the fresh air system next year. The air environment is very good for people who want to know about the problem of family environmental pollution and want to decorate their new houses. Even after the test, they can still be used as a power bank if they don't use it···
