Smart said that it has played several models, from the bulky and silly ones in the early days to the small and light ones now, all of them are dry batteries, dry batteries, dry batteries, and some need four AAA batteries, and some need three batteries. But is it really convenient? Some people may seriously think that it is very convenient. After all, batteries are convenient to buy, install and remove. When not in use for a long time, you should also remember to pull out the battery, and then install it when you use it. However, lithium batteries are so popular. Why can't the smart phone adopt the design of lithium batteries? After all, is it easier to charge?

Money for Wanhuan came out, and finally saw the design of rechargeable lithium battery on a new smart scale. This is the YUNMAI Yunmai Haoqing 2 intelligent body fat called M1601 (hereinafter referred to as Haoqing 2), but the surprise is not limited to that.

This brand logo is not only simple as silk screen printing or engraving, because it also has a backlight design, which will light up when measuring.

Different brands of intelligent body grease claim that there will be some differences in appearance design and algorithm. BIA bioelectrical impedance technology is usually used, and tempered glass with high hardness is generally used as the surface layer. Some of the parts that fit the feet are metal patches, and some are ITO conductive coatings, so as to ensure the accuracy of measurement. The content of body fat scale measurement is not very different, basically including 10 body data, such as weight, fat, bone mass BMI、 Muscle, protein, visceral fat, water, body age and basal metabolic rate. The left one is a S1 intelligent body fat scale, which uses four metal patches to fit with the feet, and the right one is Haoqing2, which uses ITO conductive coating process.

BIA bioelectrical impedance measurement method uses the principle of measuring resistance to form a loop, which is why the intelligent scale surface is divided into four parts. It's just that the product S1 uses a bright metal patch, which looks obvious, while the good light S2 uses a hidden design.

Good Light 2 uses a hidden display screen, which is equipped with 1136 LED dot matrix display screen as standard. The screen area is larger and the display content is more, so you can see the measurement results and weight changes intuitively. On the built-in chip, Holtek HT45F75 fat measuring chip and BIA chip are used by Haoqing 2 to measure body data. Good Light 2 has built-in Bluetooth and WiFi chips. The Bluetooth chip CC2541 is used to connect to the mobile phone, and the WiFi chip TI Texas Instruments CC3200 is used to connect to the network. After each measurement, it will automatically synchronize to the mobile phone and the cloud. In addition, Good Light 2 also supports the alarm clock function to remind you to measure regularly.

The two smart scales are relatively similar in size. The surface is made of tempered glass, and the corners are treated with radians to avoid bumps in daily use.

Let's get to know the major changes of Hao Qing 2. First, the built-in 3000mAh lithium polymer battery, which can be said to be an innovation, has promoted the transformation of intelligent weighing from multiple dry batteries to rechargeable lithium batteries; Second, the charging interface unexpectedly uses USB Type-C interface. This charging interface appearing on the mobile phone unexpectedly uses the smart scale, which is a small surprise for the player who does not have USB Type-C mobile phone. The round hole on the left side of the charging hole is RESET, which is used to restore factory settings, while the right side is the horn hole, which means that there is an audible reminder function.

Compared with the product S1, the good light 2 adopts a fixed frame design at the edge, without worrying about the problem of body fitting. At the same time, the frame with frosting spray treatment process looks really beautiful, which is a pleasant surprise.

On the bottom, Haoqing 2 also uses the frosting and spraying process, which looks natural and beautiful. The most important thing is that you don't have to see which battery compartment at the bottom, and it looks cleaner.

On the four foot pads, the good light 2 is much larger than the S1. The design style of the big foot can make the scale more stable, more stable and safe to stand on.

Good Light 2 has a corresponding APP available for use, which is very convenient for connection and binding. It can be connected successfully once with Samsung S5 and ASUS Hawkeye according to the prompts. APP is generally used to record measurement data for comparison of body changes. It supports multi-user use. Some communities use it to publish activities or to expose users to hatred. Haoqing APP also includes these common functions in terms of functions, which are divided into home page, community and me.

In this way, it feels weak and boring. There are pictures and truth, so pictures are still needed. On the home page is the part related to yourself, where you can view the measurement data and body report after automatic synchronization, as well as the trend chart of your body changes. In the daily challenge section, there are some activities in progress, such as the activity of bearing weight and receiving red envelopes. In the actual experience, when your weight changes more than 1.5KG, the APP will judge that the change is huge, and then a dialog box will pop up asking whether you are yourself. You can choose to be or create new members according to the actual situation.

The community is a place to see others. Of course, I also leave messages and posts. One of the fun is that there are always a lot of beautiful women sending photos, which can satisfy the eyes. The other is that there will be some video teaching and related knowledge about fitness and slimming for reference. The content is very rich and practical, which has certain reference value.

My part is about settings. You can design your own fitness goals, or you can add your family members to your family account to use the same Good Light 2. You don't need to download the app to install and register, but you can also use it directly in the visitor mode. In addition, you can set an alarm clock to remind you to measure on time. However, another highlight is that you can connect and bind the APP related to motion monitoring in your mobile phone to synchronize the motion data. For example, S Health in Samsung S5 will synchronize part of the steps and display them under the step counting function in the body report, that is, the step counting function of the smart scale. However, if you support binding the sports bracelet, you can install one less APP, More content to view.

But one problem is that the alarm clock set will not ring on time, and there is no response from the APP and smart scale. We look forward to the manufacturer's subsequent firmware version update.

Now let's begin our formal experience. As a scale, we should first meet the requirements of accurate measurement. Place Haoqing 2 on the flat ground and activate the smart scale with a single foot. This is the measurement data more than an hour after the meal. Whether squatting, standing or squatting, the reading is this value, and the measurement results will not change (I wear more clothes in winter, and I still hold a SLR, OK, it seems that I am fat). The synchronization of measurement data is relatively timely. Basically, when the measurement is completed, the APP will also complete data synchronization. The barefoot measurement is really cool in winter, and it is not recommended for pregnant women and children. Do you have to measure barefoot? If you are only measuring your weight, you can wear a sock, but if you are testing body indicators, you must measure barefoot to ensure the accuracy of the measurement results.

Product S1 is consistent with Good Light 2 in terms of measurement. At least in terms of the basic function of measuring weight, all intelligent scales will not differ greatly or be consistent in measurement results.

What about the sensitivity of measurement? I wanted to take a bottle of water for measurement, but it was too boring. Instead, I poured a glass of 420ml pure water (a beaker with a scale) and tried to measure the effect. There were changes. It seems that the measurement is still sensitive. Before and after each measurement, use a rag to avoid cleaning and keep clean.

So in the measurement results of 10 items of data, is there any difference between Youpin S1 and Haoqing 2? Different algorithms naturally lead to different results. Below are the ones with the same height, sex, and age, but the differences in the main BMI data, basic metabolic rate, and protein are the smallest and relatively close. Although the S1 test result is not as intuitive and convenient as that of Good Light 2 in display, the content of the measurement is relatively rich, with comments on body changes added, and the comments are more accurate. Recently, I did stay up late and live irregularly. Good Light 2 can also add comprehensive comments on weight changes and provide some corresponding exercise methods for users to refer to.

To make a brief summary and comment, the first big surprise that Good Light 2 brings to itself is that it abandons the traditional design mode of dry battery and adopts Type-C interface, which is worthy of affirmation. In terms of appearance design, it is simple, fashionable and compact. The hidden display makes the measurement results more intuitive to see the measurement results and changes of weight. Through the matching APP, you can learn the specific conditions of various parameters of the body in detail. The binding and matching with the mobile sports APP also improves the use of the Good Light 2. However, there are also some problems in use, such as the alarm clock does not remind on time, and there is no sound prompt. Since it can be connected to the Internet and the screen area is large, there are many contents that can be displayed, such as real-time weather conditions and corresponding icon prompts in different modes. Of course, it is better to add voice prompt function. After all, there is a speaker design.
