Internet of Things IoT

 The Internet of Things (IoT) refers to the network of physical devices, vehicles, home appliances, and other items embedded with sensors, software, and connectivity, allowing them to collect and exchange data.

Characteristics of IoT

1. *Connectivity*: IoT devices are connected to the internet, allowing them to communicate with each other and with humans.

2. *Sensors and Actuators*: IoT devices are equipped with sensors that collect data and actuators that perform actions based on that data.

3. *Autonomy*: IoT devices can operate independently, making decisions and taking actions without human intervention.

4. *Real-time Data*: IoT devices generate real-time data, enabling immediate insights and actions.

Applications of IoT

1. *Smart Homes*: IoT devices can automate lighting, temperature, security, and entertainment systems in homes.

2. *Industrial Automation*: IoT devices can monitor and control industrial equipment, optimizing production and reducing downtime.

3. *Wearables and Health Monitoring*: IoT devices can track fitness, health, and wellness metrics, enabling personalized insights and recommendations.

4. *Transportation and Logistics*: IoT devices can optimize routes, track shipments, and improve supply chain efficiency.

Benefits of IoT
