Xiaomi Mi Smart Scale 2 (White)
Accurate enough to detect you drinking a glass of water.
High-precision sensors accurately sense how the body changes every day
Mi Smart Scale 2 uses a high-precision manganese steel sensor, which can accurately sense subtle changes down to 50g. Every meal you eat and every glass of water you drink can be easily quantified, and displayed as kilograms, or pounds, effectively helping you to finely manage information about your weight.
Mi Fit APP renders your movement curve
Open the Mi Fit APP and you can view curve plots of your data and body changes anytime and anywhere. You can clearly see your transformation process. You can also make fitness plans and dietary adjustments based on your BMI (Body Mass Index). Also, your weight data will be automatically uploaded to the cloud each time via the APP and stored without limits, with there being no limit.
Lower weight is not necessarily better. Keeping an ideal weight is healthiest.
Mi Smart Scale 2 is equipped with an ideal weight measurement function, which intelligently calculates your weight based on your height, age, BMI and other data.
To maintain a stable body, being able to balance oneself is essential 
Balance is a basic physical ability. Improving balance can reduce the risk of falls and joint injuries. Mi Smart Scale 2 is equipped with a body balance ability test. Standing on the scale with one foot and eyes closed, you can learn about your body balance ability using the APP.
Intelligent analysis automatically identifies every family member
Mi Smart Scale 2 can automatically identify members of the family based on body data, and can support up to 16 members, when the device is shared by the whole family. A guest mode can also be set so that the measurements of others can be made without being stored.
Weigh a baby being carried and monitor the growth of the baby
Mi Smart Scale 2 supports weighing infants while carrying them. Parents weigh once separately and then weigh again with the baby in their arms to automatically calculate the baby's weight. Of course, you can also measure your pet's weight in the same way.
Bluetooth 5.0 provides a faster, more stable connection.
Mi Smart Scale 2 uses Bluetooth Low Energy 5.0, so the weight data transmission is faster and more stable. Cherish every second of your time.
