TheInternet of Things (IoT) can be described as connecting everyday objects like sensors and actuators to the Internet where the devices are intelligently linked together enabling new forms of communication between things and people, and between things themselves. Home automation can be described as the introduction of technology within the home environment to provide convenience, comfort, security and energy efficiency to its occupants. Adding intelligence to home environment can provide

The intent is to build a low-cost Raspberry Pi based Security system which includes a PIR (Passive Infrared) sensor placed alongside the Pi-camera activates the camera to take pictures upon detecting the presence of a person. This system is further branched into two sub categories, the first being the image taken by the Pi-camera sent through mail as an attachment and also including the IP address for live streaming. The second part consists of a Facial recognition system done using Microsoft Azure API and using Twilio platform to send the image captured via MMS (Multimedia Messaging Service). The smart door lock is built using a metal geared servo motor and a door latch on the hardware side and the software implementation is done by programming in JavaScript and also using an android mobile application 'Blynk' which is configured according to the need and is being used to remotely lock and unlock the latch. The user also receives a notification about the status of the door lock after it has been locked or unlocked to confirm its position.
