The device uses a fair­ly sim­ple con­cept. A small oval-shaped active mod­ule is installed in an ergonom­ic sil­i­cone bracelet. The device is pro­tect­ed from water and dust accord­ing to the IP67 stan­dard, it is fixed on the arm using a rus­tic but reli­able mount. Mi Band sits well on the hand, does not irri­tate the skin and does not inter­fere due to its com­pact size.


The main part of the mod­ule is made of plas­tic, while the top pan­el is made of alu­minum. It has 3 indi­ca­tors that can flash blue, red, orange and green. In addi­tion, there is a vibra­tion feed­back for noti­fi­ca­tion of an incom­ing call or alarm.


To con­nect to a smart­phone or tablet, the Blue­tooth 4.0 LE pro­to­col and the Miband appli­ca­tion, avail­able only for Android devices, are used. The pro­gram is need­ed to con­fig­ure and man­age the smart bracelet. The main fea­ture of the Mi Band is the cal­cu­la­tion of the steps tak­en per day. The func­tion works very accu­rate­ly thanks to the algo­rithm for fil­ter­ing steps from oth­er hand move­ments. At the same time, the appli­ca­tion even counts the calo­ries burned. The sec­ond impor­tant func­tion is sleep track­ing with a smart alarm clock that wakes the user up in the light sleep phase for the quick­est and eas­i­est awak­en­ing with a boost of ener­gy for the whole day.


With dai­ly use, the smart bracelet can work up to 30 days with­out recharg­ing, so you do not have to dock the device every day to replen­ish the charge overnight.
