【 Intelligent Scale Scheme Design 】 Development of Fat Scale PCBA Scheme

The intelligent fat scale adopts BIA bioelectrical impedance technology. Users only need one measurement to know the body's fat content, water content, basal metabolic rate, muscle mass, bone mass, protein, BMI, weight, body score, age and other eleven body data, so as to have a more comprehensive understanding of their physical condition and make targeted adjustments and improvements in a timely manner. If the fat is too high, the intelligent fat scale will remind users to exercise more, exercise more, and reduce fat content. If it detects that the protein content in the user's body is too high, it can analyze your dietary pattern and remind you to eat more fruits and vegetables.

Introduction to Intelligent Fat Scale Scheme

The intelligent fat scale solution is a set of products developed to detect human fat content. Its function is actually very simple, including weighing, recording, and the most important function is to measure the fat in the human body. Its measurement principle is also very simple. When we stand barefoot on the intelligent fat scale, a weak current will pass through our skin. Based on the principle that the fat inside the body is not conductive and the water inside the body is conductive, an effective resistance value can be detected. The body fat scale can be measured based on our age, gender, height, and other data, and can be input into the big data sample model to obtain the measurement. And this weak current will not cause any harm to the human body, so there is no need to worry.

Technical Document of Intelligent Fat Scale Scheme

1、 Intelligent Fat Scale Solution Software and Hardware Function Description:

LED display:

1. 3 ultra white LED lights

2. Display number: 188.8.8 (two decimal points)

3. Display symbols: ble, kg indicator

4. Not displaying body fat percentage (displayed on the APP)

Power supply: Three 4.5V dry batteries

Power on: Press to start the machine, and the weight on the scale reaches the starting pressure value (5 ± 2kg). Start the machine

Key: Unit key, no entity key,

Weighing range: nominal: 5-180kg,

Scale: 0.05 kg

Small weight zeroing: The minimum locked weight is 5kg, and weights below 5kg (stable value) are zeroed; 2.5kg<=weight<5.0kg, after locking the weight, it will display C flashing zero; Weight<=-2.50kg, display C brushing zero

Zero point adjustment range: Automatically perform zero point adjustment when the system is turned on and<2.5kg

Memory weighing value:

If the weight is weighed again but the difference between the measured value and the last measurement is not within the range of 0.3kg, unlock and re-enter the weighing function,

2. The memory function is effective when the weighing value is ≥ 6kg,

3. Starting condition for memory time: device shutdown sleep (memory time of 30 seconds)

Power on and reset to zero:

1. Display all segment codes when powered on

2. The system displays "0.00kg" after setting zero point
