What is IoT?
The Internet of Things (IoT) refers to the network of physical devices embedded with sensors, software, and connectivity that enable them to exchange data. These devices range from simple household appliances to complex industrial tools. IoT technology enhances automation, efficiency, and data collection capabilities.
As the number of connected devices grows, so does the need for secure communication. Ensuring that IoT devices can communicate without compromising data integrity is a critical challenge for developers and users alike.
Key Features of IoT
- Interconnectivity between devices
- Real-time data collection and analysis
- Automation capabilities
- Scalability for various applications
Raspberry Pi Overview
The Raspberry Pi is a compact, affordable computer that has become a popular choice for IoT projects. Its versatility, combined with its low cost, makes it an ideal platform for both hobbyists and professionals. The Raspberry Pi can be configured to act as a server, gateway, or controller for IoT devices.
Key advantages of using a Raspberry Pi for IoT projects include:
- Open-source software compatibility
- Wide range of GPIO pins for hardware integration
- Support for multiple programming languages
- Active community and extensive documentation
Secure Connection Methods
Securing remote IoT connections is essential to protect sensitive data and prevent unauthorized access. There are several methods to achieve this, including encryption, firewalls, and secure protocols.
