Smart Apartment Security using IoT Technology

Mobile devices have been integrated into our everyday life. Consequently, apartment security is becoming increasingly prominent features on mobile devices. In this paper, we have developed a security system that interfaces using IOT and Android mobile device. The mobile device and embedded security unit communicate via IOT. The mobile application can be loaded onto any compatible device, and once loaded, interfaces with the IOT security system. If a person approaches a home, he/she should enter their four digit secret number using keypad in the embedded security unit. Microcontroller in embedded security unit sends that secret number to PC .which will be uploaded in server. Android Application installed in mobile app keeps on monitoring server and fetches if any number is updated in it. After fetching number, the messages will be come to our mobile device. If the no is matched with four digit code, now user can send access code to the user if he/ she is interested. The secret code is sent to guest mobile using GSM and to the embedded security unit using IOT. If the guest enters password using keypad, it will check with the secret code and opens the door if it matches.
