The fast-paced and irregular eating habits of modern people make it easy for many people's weight to soar, especially for girls who may become overweight if they are not paying attention. Losing weight has become a major concern for many people. To do a good job, one must first sharpen one's tools. To lose weight, one must also have a good partner: scales that can only display weight simply are outdated, and intelligent body fat scales that can measure body fat are the mainstream today. The intelligent weight scale we have developed can measure eight major indicators: muscle content, water content, calories, body weight, BMI, bone density, fat content, and visceral fat content, truly achieving one scale to monitor daily body changes. And in conjunction with the app, it can help record each measurement information, form a health database, generate health recommendations, regularly remind measurements, and monitor body changes.
1、 Introduction to Intelligent Weighing Scale Scheme
Intelligent weight scales can analyze our weight levels. As is well known, different heights and weights correspond to different weight levels. Only by combining these two aspects can we calculate our own obesity status. However, the average person does not know how to analyze and combine the two to calculate their own weight level. So with this smart scale, you can directly display your weight level on the app on your phone, allowing yourself to have a clearer understanding of which level you are in. In order to better monitor and manage one's own weight.
At the same time, the intelligent weight scale will provide diet recommendations on mobile apps based on your weight level. This advantage is that we can clearly know what we can eat without a professional nutritionist, and eating those things will be more beneficial for us to control our body weight. For example, if a relatively obese person eats something high in calories and fat, it will increase their own weight burden. And if when we know what to eat? We can avoid such situations through our own control, thereby better controlling our weight and achieving a healthy physical condition.

3、 Introduction to the Functions of Intelligent Scale
Weighing scales may seem like ordinary items, but they have also become a gimmick. By giving them a new definition through the word 'intelligent', intelligent weighing scales are not just about measuring a person's weight, but can also measure multiple data. In addition to measuring body fat rate, the intelligent weight scale can also be connected to a mobile phone to automatically record daily measurement data. Some models can also share receipts on your exercise bracelet to help you develop a better exercise plan.
The intelligent weight scale can also detect 8 data items in the human body: weight, water content, visceral fat content, muscle content, fat content, overall BMI health data, basal metabolism, and bone density content. By combining measurement values, analyze the user's physical condition in detail and provide relevant health recommendations.
In addition, the intelligent weight scale cloud data is the core of the entire product. The APP supports automatic recording of personal health databases and daily weight data, and supports cloud storage without losing data even when changing phones.
4、 Development of Intelligent Weighing Scale APP
The intelligent weight scale app can help users manage weight measurement standards and monitor their body weight in real-time. However, the real-time weight bearing of the scale is displayed, and users can only see the current weight indicator. The development and customization of the intelligent weight scale app can record and save user data information on the scale, forming a weight data report, which can be saved through Bluetooth connection to the device.
1. The functions of developing an intelligent weight scale app

5、 The characteristics of intelligent weight scales
Intelligent weight scales are popular among users due to their excellent reliability, accuracy, principle technology, and simple structure. The use of intelligent scales in commercial activities is becoming increasingly widespread, bringing convenience to people's economic life.
1. The most basic function of an intelligent weight scale is to weigh the weight. After standing up for three seconds, the intelligent weight scale can display the weight very accurately.
2. Turn on the alarm function, and the intelligent scale can automatically remind you of the weight. After completing the weight, the alarm will automatically stop.
3. An intelligent weight scale can quickly analyze your BMI (Body Mass Index).
4. The intelligent weight scale can synchronize your weight and health information to a private health center by connecting to WiFi.
5. Standing barefoot on an intelligent weight scale, the scale can analyze the body's fat ratio through your feet and automatically store the recorded information.
6、 The working principle of intelligent weight scales
The working principle of an intelligent weight scale is to use a force sensor to place a heavy object on the storage platform, causing the surface to deform and causing a change in the shape of the built-in resistor. The deformation of the resistor inevitably causes a change in the resistance value, which in turn causes a change in the internal current to generate corresponding electrical signals. After processing, the electrical signals become visible digital.
1. Weight measurement
The principle of an intelligent weight scale is similar to that of an ordinary electronic weight scale, which basically uses pressure sensors. The appearance of an intelligent weight scale has four contact points with the ground, where a pressure sensor is placed. The pressure sensor converts the weight of the human body into an electrical signal, which is then sampled by the processor AD and converted to obtain the body weight.
2. Body fat measurement
The intelligent weight scale measures body fat through the electrical impedance method. The specific principle is that the electrode emits a weak current, forming a closed loop with the human body. Through the principle that muscles are easily conductive and fat is not conductive, an electrical impedance value is obtained. Then, the electrical impedance value is combined with data such as height and weight to calculate the body fat rate.
7、 The Parameter Meaning of Intelligent Scale
The parameters of an intelligent weight scale include body weight, body fat rate, muscle rate, bone mass, basic metabolic rate, water content, body age, etc.
Weight: The body weight obtained by weighing naked or wearing a known weight of work clothes.
Body fat ratio: The proportion of fat weight in the human body to the total body weight, also known as the percentage of body fat, which reflects the amount of fat content in the human body.
Muscle rate: Muscle rate is a proportional value of the human body obtained by combining the total amount of human muscle with body weight, height, etc. The range of this value determines a person's physical health status and strength.
Bone mass: The content of bone minerals (calcium, phosphorus, etc.) and bone matrix (collagen, protein, inorganic salts, etc.) in bone tissue per unit volume, used to represent the health status of bones.
Basic metabolic rate: The energy metabolic rate of the human body in a clear and extremely quiet state, unaffected by muscle activity, environmental temperature, food, and mental stress.
Moisture: refers to the water content in the body, including blood, body fluids, etc.
Physical age: also known as physiological age, refers to a person's physiological age. It is a brand new concept that represents the vitality of this person's life. The level of physiological age depends crucially on a person's lifestyle and health status.
8、 Composition structure of intelligent weight scale
The intelligent weight scale includes a load-bearing plate, pressure sensor, main control board, LCD display module board, and wireless communication module board, with tight connections between each component:
1. The pressure sensor is set below the load-bearing plate and collects the gravity signal applied to the load-bearing plate;
2. The main control board is set on the lower surface of the load-bearing board, which includes a microcontroller main control module, a data acquisition module, and a data acquisition module.
3. Having corresponding ports connected to pressure sensors and microcontroller main control modules;
4. The LCD display module board is set on one side of the load-bearing board and has corresponding ports connected to the microcontroller main control module;
5. The line communication module board is integrated and installed on the load-bearing board, and has corresponding ports connected to the microcontroller main control module.
9、 Precautions for using intelligent weight scales
1. The electrical impedance method used in intelligent weight scales can result in significant data errors. The biggest culprit affecting the results of the body fat scale is movement and changes in body moisture. For example, different data can be obtained after just taking a shower, eating a meal, or exercising.
2. The generally suitable measurement time period is 1 hour after waking up, 1 hour before going to bed, and 1 hour after three meals. However, it can also be measured according to one's own habits, paying attention to each measurement at the same time every day, and then paying attention to the above points.
3. When weighing, it is better to use it in some flat and hard places, and it is better to avoid soft places, such as blankets and foam, to ensure the accuracy of data. Also, first confirm if the four scale feet are placed smoothly and if there is any overhang.
4. When weighing, it is important to stand firmly in the middle of the scale, with evenly distributed left and right feet in the center position, as this can make our data more accurate. If standing on the left or right side, it may cause some errors. Please be aware.
5. To measure body fat and bone weight more accurately, please weigh barefoot.
6. When binding the phone, confirm that Bluetooth, wireless, and sports apps are all open. If standing on the scale, there is no response. You may want to unbind, remove the battery, and then stand on it to try connecting to a new device.
7. When moving the scale, if the display screen is still lit, keep the scale feet off the ground. After placing it smoothly, the first weight reading will increase by about 2 kg, because the weight of the scale body is automatically added to the reading. After the display light goes out, stand up again and the reading will be normal. So, scales are generally placed in corners or fixed positions and should not be moved frequently, as it may have some impact on accuracy and may damage the floor.
10、 Development prospects of intelligent weight scales
With the improvement of people's living and cultural level, intelligent technology is gradually becoming widespread in our daily lives. This has led many users to think of moving electronic scale products towards the intelligent route, which is convenient for users to use and can further improve accuracy. In order to meet the needs of users, some manufacturers have conducted tests on different types of electronic scales and pushed their products to the market, which has also received good feedback. At present, the prominent features of intelligent electronic scale products include touch screen operation, fully automatic weighing, automatic weighing data recording, weighing data export, adjustable upper and lower limit alarms, optional external printer, and the ability to perform daily sales report statistics. With the arrival of the intelligent era, the development of intelligent electronic scales is inevitable, and industry insiders analyze that the development prospects of the intelligent electronic scale industry are relatively optimistic.
