preface

Since the words "haze" and "PM2.5" came into the public's attention in 2013, people have also paid more and more attention to air quality. Unfortunately, air quality has not improved as a result, but has become increasingly fierce.

only two thousand and fifteen In, the whole country suffered eleven In the second large-scale and persistent haze process, the winter haze phenomenon in Beijing Tianjin Hebei region is more serious. eleven month thirty The highest hourly concentration in some areas of Beijing and Hebei exceeded nine hundred Microgram / M3, Beijing Liulihe Monitoring Station nine hundred and seventy-six Microgram / cubic metre. Such shocking data makes me hesitate to go to the capital for development - it's not to make money, it's to kill!

Living in such an environment makes people form the good habit of "going out with a mask". PM2.5 masks, air purifiers and environmental monitors also came into being. In this era of "mainly looking at temperament", What I want to introduce to you is a model called“ 720 Environment Treasure Plus ”Environmental monitoring equipment.

packing

♀ Throughout the packaging color of intelligent hardware, the mainstream is black and white. Home products are mostly packaged in white, giving people a clean and warm feeling. This Environment Treasure Plus is also packaged in a white paper box. The five bold characters of "the best gift" on the front add a lot of color to the package. In the upper left corner is the 720 brand. In fact, I was curious about why it was called 720 at the beginning. In fact, "720 refers to a state of harmony between body, mind and environment by giving consideration to both inside and outside of the body and the environment.". The striking "Lei Feng Trial" label in the upper right corner gives people a sense of mission. After a little complaining, at first glance, I really don't know what the product is inside. It is suggested that the product name be printed on the front.

♀ There is a product information label on the right, which seems only white at present.

♀ A notice is posted on the back of the box, indicating the activation method and purification steps. The red border is more eye-catching. There are also 720 health butlers sticking the seal. From here, we can see the opening mode of the box. In fact, this kind of lid type buckle seal has strict requirements on the scale. It is too loose to seal, and too tight to open the lid. It is just right.

♀ Uncover the box cover and see that the Environment Treasure Plus is embedded in a black high-density sponge. There is also a layer of sponge on the box cover to ensure that it will not be damaged during transportation. In addition, the outside of the product is sealed with a plastic bag, which is moisture-proof, and has finger grooves for easy removal. The data cable is in another small slot.

♀ Print a family photo: 720 Environment Treasure Plus, data cable, instructions, stickers, QR code&precautions.

Appearance&Design

♀ The 720 Environment Treasure Plus is really small enough to be a treasure in your hand. The clean white plastic fuselage is wrapped with arc, which reduces the sharpness and increases the intimacy. The 720 brand name is engraved on both sides of the front and back, giving people a simple and generous feeling. It weighs 175g and is relatively light.

♀ The bottom is printed with product information, and the middle is a cooling hole. Although the machine will not generate heat in the process of detecting the environment, after all, the time is short, but there will inevitably be some temperature in the process of charging and discharging. With these cooling holes, the heat can be basically ignored.

♀ In addition, as a device that can measure temperature, if it generates too much heat, the accuracy of data will be affected. In this way, such a large cooling hole is still necessary. In fact, there is a little distance between the cooling hole and the contact surface, so even if the cooling hole is placed downward, it will not be closed. However, I still recommend that the cooling hole should not be placed downward when using, and it is better to keep the airway smooth.

♀ Place the equipment horizontally, and half a circle of silver lines outline a kind of splicing beauty, the collision between plastic and metal. The four corners do not touch the bottom surface, which shows that the manufacturer has taken care of the design.

♀ There is a noise detection microphone, Bluetooth PM、 The four indicators of formaldehyde and noise will light up with the test items during the test. There is also a touch of orange crescent on the left, which should be used for decoration.

♀ There is only one operation button on the whole body, which is used to activate, pair and check the power. One of the magic weapons of this Environment Treasure Plus is that it can act as a mobile power supply. It has a 3600mAh polymer battery, which is safer. It is convenient to temporarily charge the mobile phone. There are 4 power indicators on the left, and charging interfaces on the right.

♀ The dedicated data line is about 50cm long and printed with 720 logo, which I like. In this way, the line will not be mistaken. In addition, although the Environment Treasure Plus itself cannot store data, it is equipped with a data cable, which can also be used by other devices for data transmission. The voltage and current of the Environment Treasure Plus are similar during the charging and discharging process. It can be seen that fast charging is not supported.

♀ Equipment parameters

APP&Use

♀ Download and register the APP first. You can scan the QR code in the manual to download the APP, but once you open it, you will be prompted to upgrade. The upgraded APP is called "environment review". Sign in with your mobile phone number.

♀ For the first time of use, you need to activate the Environment Treasure Plus, connect it to the power supply, and the power indicator lights up (if it is a grid, charge it immediately). The environment indicator lights up alternately. With a beep, the startup is completed.

♀ Open the APP, and the Bluetooth of the mobile phone will automatically start. Pairing will be performed first. Press and hold the operation button for about 2 seconds, and the blue Bluetooth indicator flashes. After the pairing is successful, it turns green and turns off, and then you can measure.

♀ Since the formaldehyde sensor will be covered by pollutants in the air if the equipment is not used for a long time, which will affect the measurement accuracy, it is necessary to clean it according to the notice on the packaging box. Quickly click the operation button for 5 times, the formaldehyde green indicator lights up, and put the equipment in clean air for 12 hours. So the problem is, where can I find clean air without an air purifier? I put it in a clean place at home, and it will be ready for one night. The temperature outside is too low, so I'm afraid it will freeze.

♀ After purification, it can be used. The detection of the environment by Environment Treasure Plus needs to be completed in cooperation with the APP. There are five major items in the APP interface. The "environment circle" can view the attached places. It has map navigation and can focus on and expose the environment of the places. Unfortunately, there are no pictures and it is not beautiful enough to look at. Maybe there are not many people around and no detection data is found. In addition, there are real-time environmental data from the environmental monitoring station.

♀ Before changing the environment measurement every time, remember to place the Environment Treasure Plus in the environment to be measured, and then measure it 15 minutes later, so that the internal environment of the machine can be balanced with the external environment. In order to obtain more accurate data, multiple measurements are also excellent.

♀ The "Environment Treasure" interface can measure the environment. Click "Start measurement", you can choose to conduct "comprehensive measurement" or "formaldehyde special measurement". The comprehensive measurement can measure five items of data: temperature, humidity, noise, PM (inhalable particles) and formaldehyde. The first three items were quickly measured in a few seconds, and the last two items were slightly slower, about 40 seconds. Since it is necessary to inhale air for measurement, the sound of the motor will be emitted at intervals, which is harsh in a quiet environment. Click "Stop Measurement" to end the test, and corresponding suggestions will appear. What is suitable for this environment. "Click me to enjoy life" will recommend water purifier.

♀ The "formaldehyde special measurement" can only measure the formaldehyde data, which takes a long time. The longest measurement is 10 minutes. Of course, the longer the measurement time is, the higher the accuracy of the results will be. Formaldehyde concentration exceeds 0.1mg/m ^three It exceeds the standard. If you live in such an environment for a long time, your body will have problems. At the end of the measurement, "aldehyde removal service" will appear, and corresponding aldehyde removal products are recommended.

♀ Click the exclamation mark in the upper right corner during the measurement to display the help information, which is actually the interpretation of the measured value to see whether the measured data exceeds the standard.

♀ After the measurement, the results can be shared, and you can take a picture or attach a picture. For privacy, you can also set not to display location information here.

♀ In the "Environment Mall", you can buy purification products and place orders directly, which is very convenient. At present, the product variety and quantity are not enough, and I believe it will be more and more perfect in the later period.

♀ "Discovery" is a tip about life and mothers and babies. There is a lot of information under the category of mothers and babies. It is suggested to add some health tips for other people.

♀ The My interface can view historical data, orders, device pairing, etc. I found that the measured data cannot be saved when there is no network. I hope this can be improved.

Measured

♀ First, let's see the accuracy of temperature measurement, which is almost the same as the result measured by the thermometer at home, with an error of about 1 ° C.

♀ Just in time to install the house, the construction master was pasting wallpaper that day. It is said that the environment-friendly glutinous rice glue was used. But before, the ceiling, cabinet, latex paint and other things, plus the wallpaper did not allow ventilation, so the house still had a strong smell of decoration. It was sure that formaldehyde exceeded the standard. After spending the afternoon, I felt uncomfortable with my voice and eyes. I can't stay in such an environment often! Note that the PM at this time is 67, which is not bad.

♀ At this time, two supervisors came and smoked two cigarettes, and then the PM reached 457! Serious pollution! The power of two cigarettes is so great! Smoking is harmful to others and oneself

♀ A special measurement of formaldehyde was made around the cabinet (density board+particleboard), 0.15 microgram, exceeding the standard.

♀ Basically, the installation is finished, and the environment is measured. The furniture is made of boards, density boards, wood floors, and formaldehyde content is a little high. Therefore, the newly installed house cannot be moved in immediately. Let it hang for two months and then have a look.

♀ Put the Environment Treasure Plus in an airtight wardrobe and let it stand for half an hour. The formaldehyde content is higher. Although it is made of environment-friendly materials and has no peculiar smell, formaldehyde, which is a terrible thing, must be detected accurately and reassuringly by an instrument.

♀ In fact, the weather was very good that day. It was rare that the sky was so blue. The test outside shows that PM is basically 0.

♀ A nearby supermarket had an event and was crowded early in the morning. It was the first time I saw so many people in the supermarket, and the special price goods disappeared in a flash! I petrified when I saw the speed of grandma and grandpa grabbing goods! I can only wait and see. Although there are many people and noises, the air is still very good. The PM is only 2. It seems that the merchants should have air purification equipment.

♀ Measured in a large shopping center, there are many people on weekends, and the PM value is good, noisy and dry.

♀ The cold wave is coming, the rhythm of freezing death! The number of people choosing public transportation has also increased. Let's have a look at the environment of the bus, a means of transportation that people often take. After a rough calculation, there are about 80 people in the bus I take during the rush hour. In such a crowded, narrow space without windows, PM is also excellent. I think it is due to two factors: 1. No smoking in the bus; 2. At each station, the door will be opened to get on and off, and fresh air outside can enter (PM drops to about 10 at the moment of opening the door each time). There is heating in the car, so it is a little dry. People in the car talk to each other and the vehicle radio makes it noisy.

summary

In fact, from the name of "Environment Treasure Plus", there was a generation of products before. Although I haven't used it, I found that the main difference between the two is the measured data. The first generation is to detect TVOC (harmful gases: formaldehyde, benzene, cigarettes, alcohol, etc.), and the Plus is changed to formaldehyde. Other data are the same. In fact, I feel that the data of benzene and cigarettes are also very good, of course, independent measurement. In fact, the Environment Treasure Plus launched by 720 has a broad market prospect. The biggest advantage is that it can be used as a mobile power supply. The biggest disadvantage is that there is no screen to display data intuitively. It is recommended to add it to the next generation. The price of its 559 is average.
