FYP 2 - Week 11

TESTING PROJECT

This is a result of the overall project after all testing, development and design finally has been successfully build and completed. This system can be used for house, office that used for door lock security using fingerprint. From picture below it shows when I has been successfully register or enroll the thumbprint and ready to access the house to access the system.

Fingerprint scanning to access the house

After the scanning fingerprint, the fingerprint sensor will identify and will process send to Arduino and will trigger solenoid to unlock the door, if not, the solenoid will lock until it gets a right thumbprint.

From picture below it shown the solenoid before scanning fingerprint the solenoid will lock and after the fingerprint the solenoid will unlock. It means, when a door via a solenoid, it is using basic electromagnetic forces to control the lock. The solenoid fits in the locking mechanism and, when locked, will expand so the device cannot be unlocked by sheer force. An electromagnetic force, such as a keycard, is needed to tell the solenoid to move, allowing the device to unlock and open.

Solenoid will lock before fingerprint scanning happen

Solenoid will unlock after successfully scanning

While the locking solenoid will keep the device locked, it is not technically on when in locking mode, because no power is being used. The solenoid only needs power when unlocking and, because most devices are consistently locked, very little energy is ever required by the solenoid. For this reason, most solenoids run on battery power, and the battery rarely needs to be changed, but in this project, the supply adapter is used for that battery.

After the fingerprint a solenoid process, the data fingerprint that user scan fingerprint from figure 4.10 will send to android application which is web server. Web servers are computers that deliver (serves up) Web pages. Every Web server has an IP address and possibly a domain name. For example, if users enter the URL http://192.168.0.2 in browser, this sends a request to the Web server whose domain name is 192.168.0.2. The server then fetches the page named 192.168.0.2 and sends it to browser.

After fingerprint scanning, the data will sent to android application to show I access the system

It shown the data user when I scanning fingerprint to enter the system. With this, I can only access that IP address from home. This means I must be connected to the same router that user has Ethernet shield is connected to. That picture is from I accessing webserver with my Android Smartphone.
