IoT devices are nonstandard computing devices that connect wirelessly to networks and transmit data. The Internet of Things (IoT) describes the network of physical objects embedded with sensors, software, and technologies to connect and exchange data over the internet. IoT devices share collected sensor data by connecting to an IoT gateway or edge device where data is sent to the cloud for analysis or analyzed locally. IoT is used in traffic management through cameras and sensors that count cars and adjust traffic lights, and enable immediate communication with hospitals during accidents. However, IoT faces drawbacks of dependence on power supply and networks.

2. What are IoT devices??
The IoT devices are nonstandard computing devices
that connect wirelessly to a network and have the
ability to transmit data

3. What is IoT??
The Internet of Things (IoT) describes the
network of physical objects—“things”—that
are embedded with sensors, software, and
other technologies for the purpose of
connecting and exchanging data with other
devices and systems over the internet

4. How does IoT work??
• IoT devices share the sensor data they collect
by connecting to an IoT gateway or other edge
device where data is either sent to the cloud to
be analyzed or analyzed locally.

8. Advantages of IoT
• Improved productivity of staff and reduced
human labor
• Cost-effective operation
• Better business opportunities

9. How IoT is used in Traffic
management??
• Management and Prevention of Road – Accidents
• Cameras and Sensors

10. Management and
Prevention of Road - Accidents
• The most important element here is immediate
communication with the hospital or authorities.

11. Cameras and Sensors
• Various sensors and video cameras may be put at various
locations along the road to count the number of cars . If there
are more cars on the road than predicted, the sensors might
extend the duration for the green light.

12. What Is SENSOR
•It is a device that converts signals from
one energy domain to electrical domain.

14. Drawbacks of IoT
• Power supply dependence
• Network dependence
