Raspberry Pi is a small, low-cost computer that can be used for a variety of applications, including the Internet of Things (IoT). It is a single board computer, meaning all of its components are on one board. It is powered by a Broadcom BCM2837 processor and runs a Linux-based operating system. It has a variety of ports, including HDMI, Ethernet, USB, and general-purpose input/output (GPIO) pins, which can be used to connect and control various electronic components.
Raspberry Pi can be used in IoT projects in many ways. For example, it can be used to create a home automation system, where it can control lights, appliances, and other electronics using sensors and actuators. It can also be used to create a home security system, where it can detect motion and sound and trigger alarms. Additionally, it can be used to monitor environmental conditions, such as temperature and humidity, and alert users when certain thresholds are exceeded. Finally, it can be used to create a home media center, where it can stream audio and video content from the internet.
