Thanks to Lei Feng for providing 720 Environment Treasure Plus experience I believe there are many online product related reviews. If they are the same, it is not meaningful. I'd better talk about my day with 720 Environment Treasure from the perspective of users.

The old monster grew up in the imperial capital since childhood. The blue sky, white clouds and yellow sand in his childhood have long been in his memory. I don't know when the city has always been filled with things like fog. Later, I learned about the haze PM2.5 and other terms, this thing is very harmful to people, but how can I determine where there is no, whether it is better to close the window indoors than to open the window, and how the air in the relatively closed car is unknown! I once searched for relevant measuring instruments on a treasure, and the price of thousands of dollars immediately stopped us from thinking. Moreover, the accuracy of the data needs to be proved, so this matter is put on hold; Fortunately, 720 Environment Treasure has been applied. As an intelligent hardware for air quality measurement, it is small and portable in appearance, capable of measuring PM2.5, formaldehyde, temperature, humidity and noise, and can also be used as an emergency power supply to charge mobile devices. It can be said that it has a variety of practical functions, and is really a necessary medicine (equipment) for travel and home!

Living in the capital, the morning and evening rush hour is terrible. The old monster travels more than 40 kilometers each way to and from work. It takes about 2 hours by car, and it also takes 1-2.5 hours to drive. That is to say, I have to spend several hours on the car every day. Every time there is a long fog outside the window, I wonder how the air in the car is and whether the car's air filter can filter PM2.5, Opening and closing the windows has little impact on the air quality in the car. Why not take out the 720 Environment Treasure which was fully charged in the morning for testing? The Environment Treasure with 3600mAh battery inside is small (117 * 70 * 27mm) and does not take up space in the bag. Even if it is put in the coat pocket, it will not be burdensome (175g=the weight of a mobile phone). Just parked the car, put the Environment Treasure on the dashboard, took out the mobile phone, opened the 720 "Environment Review" APP, and made a comprehensive measurement with one button. After about 25 seconds, various values can be displayed.

The above figure shows the measured data of the car just parked, including temperature, humidity, noise PM2.5、 The values of formaldehyde are all in the ideal range, of which the noise of 68dB is due to the radio in the driving car; There seems to be a lack of comparison between the values in the car. Anyway, it's not time to go to work. Open the doors on both sides for ventilation, and then measure them after 5 minutes to see what changes the values have.

From the comparison in the above figure, it can be seen that after the door is opened, the air inside the car merges with the outside world, PM2.5 rises, the temperature drops, and the formaldehyde is relatively stable. This result is similar to my expectation, satisfactory! Through the 720 "Environment Review" APP, you can share the value to social applications such as microblog and WeChat, increase the interaction between friends, and see everyone's sharing results from the map, providing a reference for going out to play and choose a destination or other activities.

Time passed quickly. I wanted to have a survey in the office in the morning, but it was noon in a twinkling of an eye. OK, take the 720 Environment Treasure to the canteen to have a meal and survey the environment there.

The canteen is really a noisy place. Other values are OK, and the noise directly rises to 78dB.

I had to work for two hours before I could take a break. The house of the unit was decorated in 2013. All the houses, floors and furniture were newly built at that time. Although I can't smell the odor for a long time now, I still have doubts about the quality of these furniture, whether formaldehyde will slowly evaporate, and it is only reliable to measure!

Ha, the result is also good, better than I expected, so I can rest assured.

In fact, we spend the longest time at home every day, especially the elderly and children. The environment of the home is directly related to the health of all families. I tested the formaldehyde in the bedroom, living room and balcony, and found that the formaldehyde in the living room exceeded the limit. After careful searching, I found that I bought the imitation linen a few days ago. It seems that it will be dangerous if I am not careful, Hurry to clean it and go to the balcony to blow.

"Comprehensive measurement" and "formaldehyde special measurement" can be carried out in the APP, which can be selected according to different needs of users. For example, we can only use "formaldehyde special measurement" to test when we purchase furniture or go to a newly opened mall.

After a busy day, 720 Environment Treasure gave me the impression that it is convenient and practical. Its body is small, easy to carry, and easy to operate. The sharing function increases social interaction. In addition to the detection function, it can also use the body power to charge the mobile phone. Although Environment Treasure can only provide 5V1A current output, it is enough for emergency use, Today, I measured about 20 times a day, and the power display was still full at night, which means that it does not consume power when it is working. Another point is that Environment Treasure is in standby mode as long as it has power. You can take out your mobile phone at any time to measure, and you do not need to open it separately.

720 Environment Treasure has broken down for a long time. I also put forward some personal suggestions for improvement. Can I shrink the volume a little more; 2. Although the cream skin like shell feels comfortable, it is also easy to get dirty. Whether to consider changing it to frosted or other materials, or add a suede protective cover; 3 Since you can charge your mobile phone, you should make more efforts to increase the output current to about 5V2A, or support the fast charging standard. Only by working hard and paying attention to every detail can you win more users' favor; 4. Can you add a small LCD screen on the body to display the measured data directly, so that users can use it completely without the phone, which will also increase costs; 5. I noticed that there will be corresponding solutions (purification, water purification, formaldehyde elimination products) recommended in the shopping malls in the APP and when formaldehyde measurement exceeds the standard. This is understandable, but as a user, I need more common sense and suggestions, such as prompting users to wear masks after detecting that PM2.5 exceeds the standard It is recommended to leave the current location or deal with some pollution sources in time after formaldehyde is detected to exceed the standard.

Finally, the 720 Environment Treasure group diagram is attached to end the experience. By the way, I will take 720 Environment Treasure out without mobile power in the future. Everyone will wait to see my sharing. At the same time, I hope everyone can join in and pay attention to our living environment!
