Four smart locks for smart locks

Mentioned earlier, smart locks have fingerprint locks, password locks, sensor locks, remote locks, and other forms, which are the most common types of smart locks on the market. The locks are unlocked as shown below.

(1) unlocked by fingerprint

The core technology of the fingerprint lock is the biometric technology, which is to unlock the keys by recognizing uneven lines on the frontal skin of the fingers. At present, medical science has proved that people's fingerprint texture features are different for each finger, so fingerprint locks use this special biological feature to verify the user's real identity.

(2) unlocked by electronic code

The electronic code lock is an electronic product that controls the mechanical switch closure through password input and completes the tasks of unlocking and locking. At present, the electronic code lock that is widely used in the market is based on a chip and is realized through programming.

(3) Unlocking via electronic sensor

The electronic induction lock sensor has a coil inside it, which is equivalent to the primary coil of the transformer. The card also has a coil, which is equivalent to the secondary coil of the transformer. When the two coils approach, a current will be generated to power the card and the signal will be transmitted. If it meets the condition, the door will open automatically.

(4) unlock by remote control

Remote lock is the use of wireless technology and Internet of things technology, through the network, Bluetooth and other wireless signals to achieve door locks and mobile phones or remote control connection.
