In my community, there have recently been a lot of break-ins due to the lack of security of traditional locks. By building a Smart Lock, we make homes safer and create greater convenience for the user by eliminating the necessity of keys.
What it does
Sense uses facial recognition and fingerprint technology to unlock doors.
How we built it
We used the raspberry pi to run the facial recognition software and attached it to a breadboard that has a button to emulate a doorbell and an LED to emulate the opening and closing of the door. We used the arduino to run the fingerprint sensor and attached to a servo motor that represented the opening and closing of the door latch.
Challenges we ran into
Both the facial recognition and fingerprint sensing technologies required a large power supply, but the microprocessors could not provide that. To combat this, we split the two different aspects of the project between the arduino and the raspberry pi. The power sources were still insufficient, but we were able to test the application using an external power source.
Accomplishments that we're proud of
We are proud of our ability to be dynamic when faced with challenges. We also continued to persevere despite the constant setbacks.
What we learned
We learned the limitations and difficulties that arise when using microprocessors such as arduino and raspberry pi.
What's next for Sense
We want to integrate the application with a relay module, power adaptor, and door strike in order to complete the locking mechanism.
