This document summarizes an internship report on a home automation project using IoT. The objectives were to automate a room's lighting system using a Raspberry Pi, IR sensor, and relay. When the IR sensor detects a person entering the room, it triggers the relay to switch on the light bulb. The light can also be controlled remotely via commands sent to the Raspberry Pi over WiFi from a mobile phone. Issues faced included connecting AC components to the Raspberry Pi safely and synchronizing the IR sensor and remote commands. The project demonstrates using IoT technologies like sensors and cloud connectivity to automate control of devices in the home.

3. 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.

4. What is the scope of IoT ?? -
IoT is a transformational force
that can help companies improve
performance through IoT
analytics and IoT Security to
deliver better results. Businesses
in the utilities, oil & gas,
insurance, manufacturing,
transportation, infrastructure
and retail sectors can reap the
benefits of IoT by making more
informed decisions, aided by the
torrent of interactional and
transactional data at their
disposal.

5. What is Home Automation ?? -
Home automation gives you access to
control devices in your home from a
mobile device anywhere in the world.
The term may be used for isolated
programmable devices, like
thermostats and sprinkler systems,
but home automation more accurately
describes homes in which nearly
everything — lights, appliances,
electrical outlets, heating and cooling
systems — are hooked up to a
remotely controllable network. From a
home security perspective, this also
includes your alarm system, and all of
the doors, windows, locks, smoke
detectors, surveillance cameras and
any other sensors that are linked to it.

6. Objective -
WE ARE REQUIRED TO AUTOMATE A
ROOM’S LIGHTING SYSTEM BY USING
THE KNOWLEDGE ACQUIRED DURING
THE IOT COURSE.

9. How it works -
Basically, the idea of my project is to automate the Home lighting system i.e. control it via phone
or via your presence. So, I integrated the both concepts and following is the processes it involves –
1. IR sensor is used to detect the entry of the person.
2. When someone enters the room, it triggers the IR sensor and makes its value to true and
switches on the Electric bulb.Then, program continuously checks whether the person has
exited the room or not, which confirmed when the person commands Off. If yes, then it
switches off the Electric bulb.
3. We can also control the Electric bulb via your phone only like a remote over internet.
4. When a command is issued like ‘On’ or ‘Off’ , the program quickly checks whether there is any
command given by the User or not and on the basis of command given by the User it switches
the light and at the same time it informs the User via quick reply.

10. • Connecting AC components with RaspberryPi via Relay.
• Confusions while understanding the internal circuitry of
Relay.
• Felt requirement of Motor controller to control the
motor.
• Felt requirement of Non-contact body temperature
sensors so that speed of the fan(if available) can be
controlled automatically using RaspberryPi.
• Logical problems while synchronizing the working of
provided IR sensor and commands issued from the
Mobile.
