Smart Door Lock System

Security plays major role in today's life; this work mainly deals with security. Here we make use of fingerprint sensor, GSM module and arduino microcontroller. The finger prints of authorized person are previously stored in microcontroller, by using matching algorithm we check whether the person is authorized or not. If the person is authorized OTP (One Time Password) has been sent to that authorized person mobile number using GSM. If the person fingerprint does not match with previously stored finger prints the he is unauthorized person so OTP will not sent to his mobile number instead buzzer will turn on indicating that someone is trying to access door. This can be implemented to the places where security place major role that is in banks, offices etc. The main aim of this research is to provide high security with low cost, because security plays major role in our society in almost every sector
