Development of Bluetooth smart fingerprint lock
It is a Bluetooth smart fingerprint lock solution development company, which is a mature solution in the collection of smart home appliance solutions. The fastest 7-day sample chip test of the program project is a kind of unlocking operation that can be performed through Bluetooth pairing of mobile phone app and smart fingerprint lock!
Development of Bluetooth smart fingerprint lock
1、 Function
1. Fully automatic lock body, push and pull in and out, one touch to open;
2. Swedish FPC semiconductor three-dimensional fingerprint sensor can only be guaranteed if it is opened faster;
3. Powerful intelligent chip, performance increased by 40%;
4. One time temporary password, more convenient for visitors;
5. 6 convenient unlocking methods: fingerprint identification, password unlocking, Bluetooth unlocking, magnetic card unlocking, key unlocking, temporary password, which can be used by the elderly and children;
6. Made of the same grade material as that of automobile, durable and durable;
7. De dual system design is adopted, and the front and rear panels operate independently to prevent the electronic control part from crashing;
8. Any two combined verification methods can be switched at will;
9. Multiple alarm functions, always guarding the safety of the home;
10. Fully automatic three prevention lock body.
2、 Bluetooth chip selection
The Bluetooth Solution Development Engineer analyzed the commonly used Bluetooth smart fingerprint lock development solutions in the market, and assessed that the ac6321a4 qfn32 model of Jerry ble Bluetooth chip series can be used as the master chip.
3、 Working principle
Bluetooth smart fingerprint lock is composed of mechanical linkage system and electronic and identification control. Combine mechanical technology, modern hardware technology, computer information technology and electronic technology. The Bluetooth is connected to the fingerprint lock Bluetooth and controls the switch of the fingerprint lock by sending an unlocking signal to the fingerprint lock.
The above is the development content of the Bluetooth smart fingerprint lock solution shared by the Bluetooth solution development engineers.
