In the kit biometric authenticated system for deices in large industries, the several appliances are operated by different users. Sometimes, it becomes necessary to make these devices to operate by authenticated users only. Here we have designed a system of devices such that each device has its different master. I.e. only the master can control it and no one else. At the time of registration for authentication, each device will be provided its master by scanning the finger print of the master. Once, the registration is done, only the master of that particular device can operate it.
In the kit biometric authenticated system for deices the finger print scanner is there to scan the finger print and store the database inside it. The microcontroller can ask it anytime to check the validity of the preset finger placed on it. If the user is valid then only the microcontroller opens and closes the gate. The appliances are controlled with the help of relays which are further controlled with relay drivers. The system can be powered up with 12V 1A ac or dc power supply. The rectifying and filtering circuit is embedded in the system. The communication link between the fingerprint scanner and the microcontroller is the UART communication. The system can be further upgraded and hence can be connected with the system where there can be a large database.
