Idea & Implementation of the project

What is IoT? Internet of Things (IoT) is an ecosystem of connected physical objects that are accessible through the internet. The ‘thing’ in IoT could be a person with a heart monitor or an automobile with built-in-sensors, i.e. objects that have been assigned an IP address and have the ability to collect and transfer data over a network without manual assistance or intervention. The embedded technology in the objects helps them to interact with internal states or the external environment, which in turn affects the decisions taken.

IoT Applications

Hardware Boards

Raspberry Pi Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games.

What is AWS IoT? ď ľ

AWS IoT is a managed cloud platform that lets connected devices easily and securely interact with cloud applications and other devices. AWS IoT can support billions of devices and trillions of messages, and can process and route those messages to AWS endpoints and to other devices reliably and securely. With AWS IoT, your applications can keep track of and communicate with all your devices, all the time, even when they aren’t connected.

Idea of the Project A bulb connected to raspberry pi is switched on/off remotely using an android app with help of aws-iot cloud services.

Components of AWS-IoT 

Device Gateway



Authentication & Authorization



Device Shadow



Rules Engine

Working 

The raspberry pi initially interacts with shadow(virtual state of the hardware device in aws-iot) to fetch the previous state of led(on or off).

Thereafter it listens to any shadow changes.



The android app is used to interact with the raspberry pi for changing the state of led by altering the shadow state.



The raspberry pi listens to the changes made to the shadow state and changes the state of led accordingly .The raspberry pi also publishes a message to aws-iot console for a particular topic.(MQTT protocol is used for this, which is based on publisher subscriber model)



The aws-iot console subscribed to same topic listens to messages and executes a rule(if required) to invoke other amazon aws services like sns,dynamo db, lambda function, analytics etc.
