Face Recognition Door Lock System Using Raspberry Pi Ppt

Connect the vcc and gnd of the relay module to 5v and gnd of raspberry pi.
Face recognition door lock system using raspberry pi ppt. Being a student of engineering we have had experience in programming but never got a chance to develop on hardware such as the raspberry pi. Because of this we will need to use an external power source and relay to operate the lock. Then connect the signal pin of the relay module to the gpio 26 of raspberry pi. On the other side of the relay module connect the negative form dc power source to the negative of the solenoid door lock.
Project description the basic idea was to develop a cost effective but efficient system for facial recognition we have used raspberry pi as the processing unit for the facial recognition system linux was used as the operating system with python as the programming language for the facial recognition system source code.
