[Preface]

Hello, everyone. I am the Three Treasures, not the Three Treasures of Good Luck. I am the third generation descendant of our family. My name is Environmental Treasure 3. You can call me Three Treasures. My grandfather said that since Pangu created the world and the Queen created people to mend the sky, the environment of the earth has been deteriorating in the wanton development and plunder of human beings, but people who only care about "money" don't think so. Is that really nothing? In order to remind people that the deterioration of the environment should not be underestimated, so that they can perceive the surrounding environment in real time, our 720 family decided to upgrade my father, so there was me, a versatile king with beauty and talent, and a small and portable environment detector. Why on earth should I say that I am the Almighty King? Am I bragging? If nothing else, I can automatically monitor 8 environmental indicators all day long, and I ask whether you are satisfied or not? I asked you if you still have sei? You want to know what kind of killer mace I have, hey hey, listen to me slowly:

[Packaging&Unpacking]

? Let's start with my clothes. It's summer. Why not wear a white shirt? White represents clean, which is our 720 family's expectation for the environment. My shirt follows the simple style. Our family name, my name and a low-key word are enough - more than eight air monitoring items. Sometimes, the more low-key, the more attractive.

? There are clothes labels on the side, which affect the appearance but cannot be absent. You know.

? My two brothers and I have taken off our clothes. How about our beautiful figure? At first glance, I may look like a small Bluetooth stereo, but I really am not.

[Appearance&Design]

? My body bone is divided into upper, middle and lower sections. The upper and lower sections are white plastic. The middle section full metal mesh will lift the grid in an instant? The fine and large mesh cover allows the surrounding air to contact the sensors inside, improving the accuracy of data monitoring. The silver and white colors are matched with a strong technical model. Now, our 720 logo must be a mirror.

? There is a button on my head and four indicators on my forehead. The function button can carry out Bluetooth pairing, check the power and restart the device. The protruding forehead makes the indicator light more obvious. The green light means reaching the standard, and the red light means exceeding the standard. You should pay attention. It can monitor PM2.5 PM10?TVOC?eCO2? Formaldehyde, noise, temperature and humidity are 8 items in total. PM is familiar to everyone. It refers to the inhalable particles in the air, which can be divided into PM2.5 and PM10 according to the size. TVOC refers to total volatile organic compounds. " world health organization (WHO)? The National Academy of Sciences/National Research Council (NAS/NRC) and other institutions have always emphasized that TVOC is an important air pollutant. The US Environment Agency (EPA) defines VOC as any carbon containing compound participating in the photochemical reaction in the atmosphere except carbon monoxide, carbon dioxide, carbonic acid, metal carbide, carbonate and ammonium carbonate. ECO2 refers to the equivalent carbon dioxide, nail alkane, nitrous oxide, halohydrocarbon and other greenhouse gases, which are calculated by TVOC.

? So is all this data useful? For example, if you often turn on the air conditioner in summer, the TVOC value suddenly increases after you turn on the air conditioner, it is likely that your air conditioner needs cleaning; Another example is that when we use humidifiers in dry winter, the PM value increases sharply after use, which means that either your humidifier needs to be cleaned, or there are too many impurities in the water, which increases the particles in the air after gasification.

? My information is printed on the bottom, and there are anti slip rubber pads on the four corners, so that I won't scratch the table or be scratched. With them, I won't run around at will.

? On the right is my sexy mouth, and all my energy must be transmitted by it. Built in 850mAh polymer battery, which can be monitored even without plugging in.

? It's not as big as slapping. "Small stature, great wisdom" means me.

[Use&App]

? Before using me, you need to download the environment review APP, register and log in, bind the device, and then start the measurement.

? I connect to the App through Bluetooth. When measuring, the corresponding light will be on. The measurement without power on is manual, and the measurement can only be performed after the App is turned on; It is automatically measured every 15 minutes when plugged in. After automatic detection is enabled in the App, you can view the environmental data remotely on WeChat, as well as historical data and environmental trends. Even if you are outside, I am the patron saint of your home.

? I recorded a video to show you the operation of the app.

Comparison

? In order not to be "wise after the event" when the threat comes, our family specially designed me to be "proactive, real-time monitoring" type, which is called preemptive. As the saying goes, green is better than blue. Here's how I am better than my father's Environment Treasure Plus (Environment Treasure 2):

? Let's start with the appearance. After all, this is an era of face. I have more delicate facial features and smaller body than my father, no matter face or body. The use of metal mesh is a high-tech product.

? My father can measure five data items including formaldehyde, noise, temperature, humidity and PM. In order to make the data more intuitive, I refined PM into PM2.5 and PM10, because people pay more attention to PM2.5, which is an inhalable particle. In addition, I also measured two more items than my father, TVOC and eCO2, especially the newly installed new house. These two data are particularly important. In addition, in terms of the design of the indicator light, my father is a small dot, which cannot be seen clearly from a distance. My light becomes larger and more obvious, so that you can see clearly from a long distance. And after the data exceeds the standard, I will send out a beep to remind the owner to pay attention.

? One of my dad's more skills than I am is that he can be used as a power bank. He has 3600mAh polymer battery built in, but mine is 850mAh. In order to reduce my size and weight, our family had to bear the pain, remove the power bank function, and focus on environmental measurement. As for the air inlet, my father has only one small hole for air intake, while I have four sides for air intake, so that I can better perceive the surrounding environment.

? My father has cooling holes at the bottom, so I don't need ventilation around here; I am "square", he is "long"; I also have four foot pads~

? I am 54g lighter than my father. Don't underestimate this 54g. People who lose weight know how much sweat and effort is needed to lose every gram of weight! Here, I would like to thank our 720 family for all their efforts before I was born.

? I admit that I can't compete with my father in terms of charging, but it's not because I want to monitor our home in real time. It's inevitable that the power consumption is fast and the charging is slow. I hope my son can make progress in this regard.

? In the same environment, my father and I measured successively, and the data obtained were very similar or even identical. My father measured that PM was 40, which was just the sum of my PM2.5 and PM10. In addition, compared with my father, the noise of the machine itself during measurement is also reduced. I have upgraded my appearance design and core measurement. Have you been impressed? Let me tell you whether the new players dare to live in a healthy working, living and learning environment!

Summary

This Environment Treasure 3 gives me a more comprehensive understanding of the surrounding environment. I used to think that more ventilation is enough, but there are many toxic and harmful substances in the air that we can't see or smell. If the weather is bad, the outside air is worse than the air at home. The effect of ventilation will only make the air at home worse. If there are often people at home, especially the elderly, children, pregnant women and other vulnerable groups, it is necessary to use this kind of environmental monitor that can automatically detect the environment in real time and can be viewed remotely through WeChat. The appalling school pollution incident in Changzhou some time ago sounded an alarm to all sectors of society. When the symptoms of environmental pollution appear on you, it is too late. Why not monitor and measure them in real time? I believe that with the continuous improvement of people's environmental awareness, more and more environmental monitoring equipment will become necessary for home and travel, but why not start now? Environment Treasure 3 is your best choice. (P.S. Environment Treasure 3 has not been listed yet.
