Shared multi-scenario multifunctional Bluetooth smart lock electronic solution

Description of development background: Locks are the most common tool in our lives. Only with locks can it be easier to manage items safely. With the development of electronic technology, more and more products are integrated into intelligence, which greatly improves production, life, work efficiency and solves problems in life. Now we integrate low-power Bluetooth technology to enable locks to achieve short-distance unlocking The solution is embodied in every scene in life in a variety of applications, improving the convenience and intelligence of unlocking.



Product use

Occasion 1:

Scenario 2: Shared cabinet lock

Occasion 3: Sharing an escort bed

Functional Overview:

1. Open the mobile APP and search for the broadcast name of the specific Bluetooth lock: key--XXXXX (number)
