INTERNET OF THINGS AND ITS APPLICATIONS

The Internet of Things (IoT) is a system of interconnected devices that communicate and
exchange data with each other over the internet or other communication networks.
 These devices are embedded with sensors, software, and hardware to collect, analyze, and
act on data, often without human intervention.
1.1.2 COMPONENTS OF IOT:
 Smart Devices: Physical objects like sensors, appliances, or machinery equipped with
IoT capabilities.
 Sensors and Actuators: Sensors collect data (e.g., temperature, motion), and actuators
perform actions (e.g., turning off lights).
 Connectivity: Devices use Wi-Fi, Bluetooth, Zigbee, 5G, or other networks to connect
and communicate.
 Data Processing: Data collected is processed locally (edge computing) or sent to a
central server/cloud.
 User Interface: Apps or dashboards allow users to monitor and control the devices.
1.1.3 WORKING OF IOT:
 Data Collection: Sensors embedded in IoT devices collect data from their environment
(e.g., weather conditions, health metrics, or machinery status).
 Communication: Data is transmitted via the internet or a private network to other
devices, edge systems, or cloud platforms.
 Processing and Analysis: The data is processed using AI or machine learning algorithms
for real-time analysis or predictive insights.
 Action: Based on the analysis, devices perform actions autonomously or notify users.
1.1.4 KEY APPLICATIONS OF IOT:
 Smart Homes: Devices like smart thermostats, lights, and security cameras enhance
home automation.
 Healthcare: Wearable devices monitor patient health and send data to medical
professionals.

 Industrial IoT (IIoT): IoT optimizes manufacturing processes, predictive maintenance,
and supply chain management.
 Smart Cities: IoT systems improve traffic flow, waste management, and energy
efficiency.
 Agriculture: IoT sensors monitor soil conditions, weather, and crop health for precision
farming.
 Retail: Inventory tracking and personalized customer experiences are enhanced with IoT.
