Biometric relay switch
Biometric relay switch power on, the module keep in working condition, that is power on state:
Press the fingerprint once, success, output Output High Level
Press the fingerprint again, success, Stop output
Power on, the module keep in working condition, that is power on state:
After the fingerprint is successfully verified, the output level is 0.1-550 seconds (adjustable).
Finger start module, output high level 0.1-550 seconds (adjustable) (mainly connected to electromagnetic lock or relay)
Finger start module, output forward rotation for 0.5 seconds, stop 5 seconds, reverse for 0.5 seconds (mainly applied to fingerprint door lock)
Biometric fingerprint control switch relay
Fingerprint matching has been successfully used by law enforcement for more than a century. The technology is now finding lot of other applications such as identity management and access control. In this context, an automated fingerprint recognition system and identification of key challenges are described along with the
The Biometric relay switch description is like a product design in this report implementing RTOS (Real time operating system) under the domain of embedded system. Fingerprint Recognition is a widely popular but complex pattern recognition Problem. In this paper, we have come with a novel approach to solve the existing problems with a proper Embedded System Design. In this project as well the fingerprint detection makes it coherent with the application involved within. The solutions viable are never ending but the switching mechanisms are to be sought after.
Biometrics is the measurement and statistical analysis of people’s
physical characteristics. The technology is mainly used for the
identification and access control of various switches for identifying
individuals that need surveillance or automation.
Fingerprints are the prominent physiological characteristic of the
human body. In order to protect users of computer systems and
to secure network-based transactions, demand is increasing for
improved user authentication procedures to establish the identity
of an actual user and to bar access to a terminal to anyone who is
Personal identification Biometric relay switch using biometrics, a person’s physical or behavioral characteristics, has come to attract increased attention as a possible solution to this issue and one that might offer reliable systems at a reasonable cost.
While traditionally this technology has been available only with such expensive, high-end systems as those used in law enforcement and other government applications, today many personal-level applications have also become possible thanks to the advancements in pattern recognition technology. Fingerprint sensors can be made small and thin enough to be implemented easily for small applications and even on pocket-sized terminals.
The major advantages presented through the usage of biometrics
and finger print detection are stable, reliable and highly accurate
identification software is currently available even for use on
Thus we come across the enabling of this sensor which is efficient
and not expensive to be the middle ground for the working class
to optimize the surroundings. The main advantage of this project
is to enable the switching or even enrolling any device for the
change in the state of a system.
User Based Device control using fingerprint sensing. We come
across areas where we need to switch no device for a particular user as soon as he enters. The device could be his Pc, fan, lights etc.
For this purpose we suggest a fingerprint based device switcher project. The system switches on device for a particular user automatically on sensing him through his fingerprint scan. For this we use a fingerprint scanner interfaced to a microcontroller based circuit. As soon as a person enters he/she is allowed to scan his/her finger on the scanner. On scanning the data is sent to the microcontroller, based on this data the scanned copy is now verified for authentication.
If the user is verified the microcontroller switches on a device
(light) to indicate as the users verification. A single device can be used for multiple functions and this rectifies the problem of having different access keys. The main principle of this device however is the way a single person being able to control all the different accessing switches with different fingerprints reducing the redundancy of having multiple devices or physical switches.
