Security is becoming an important issue everywhere nowadays. Every person wants his house, factory; bank etc to be secured. House security is becoming necessary as the possibilities of intrusion are increasing day by day. In this paper, door security system has been designed that has a unique feature. Arduino was used, which is considered one of the modern programmable device. In this security system we are using a finger print sensor for a better security performance. This paper aims to develop a door security system using arduino uno, fingerprint sensor , solenoid lock , power supply, Relay module and so more . processed by Arduino UNO board which act as microcontroller unit.

Arduino uno, fingerprint sensor , solenoid lock , power supply, Relay module.
