How OSOL Fingerprint Lock Works

The working principle of smart fingerprint lock: The human skin consists of three parts: epidermis, dermis and subcutaneous tissue.
Fingerprints are raised lines on the epidermis. Due to the genetic characteristics of human beings, although fingerprints are available to everyone, they are different. No two fingerprints have been found in the entire world to be identical. Its shape characteristics are fixed.
The working principle of the smart fingerprint lock II: According to the uniqueness of each person's fingerprint, it is determined that the fingerprint is used as the key.
Through pre-archiving in the system, the individual's fingerprint is stored in advance. When the user needs to access, the fingerprint sensor collects the fingerprint information of the user, passes the fingerprint feature value to the fingerprint identification chip for analysis and comparison, and determines whether the user has the right to access.
Smart fingerprint lock works three: set permissions
If the user has the necessary authority, after the verification passes, the fingerprint identification chip outputs the control signal to drive the gated DC motor to achieve the control of the door; if the user does not have the corresponding authority, the verification will give the verification failure information.
Smart fingerprint lock works four: experience summary
Many people are now doing fingerprint lock installation. The market for fingerprint locks is very large. The benefits of installation are not discussed today. Let's look at the working principle of fingerprint locks. Are fingerprint locks safe? These should be all comparisons. concerns, the human body is a kind of fingerprint lock smart lock with fingerprint recognition and support means, it is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. Fingerprint locks generally consist of two parts: electronic identification and control, and mechanical linkage system. The uniqueness and non-replicability of the fingerprint determines that the fingerprint lock is the safest kind of lock among all the current locks.

Hot Melt Adhesive For Air Filter Sealing

A hot melt filter is a device used to filter air or liquid. It consists of a filter layer with porous structure formed by melting and curing of hot melt adhesive fiber. The hot melt glue filter has the following characteristics:

1. Efficient filtration: The hot melt glue filter has high filtration efficiency and can effectively filter small particles and suspended matter, such as dust, bacteria, viruses, etc.

2. Low resistance: The porous structure of the hot melt filter enables the smooth passage of air or liquid, reducing resistance and improving filtration efficiency.

3. High transmission electron microscopy
