Explain how IoT works.
The brains of Internet of Things gadgets are AI systems. Sensors, cloud infrastructure, data-processing applications, and state-of-the-art user interfaces are just some of the parts that make up the Internet of Things. Connected sensors and other devices constitute the backbone of Internet of Things (IoT) systems. With a quadcore CPU, a Raspberry Pi may serve as a "gateway" for Internet of Things gadgets. It is a tiny computer the size of a credit card, and it has GIPO (general purpose input/output) pins for controlling outputs and sensor pins for gathering information about the physical environment. Real-time data is collected by a sensor and uploaded to a cloud server. When information enters the cloud, it may be analysed and used to trigger events like alerts or hands-free device adjustments.  If the system needs input from the user or if the user just wants to see how things are doing, they may do so via the user interface. After the user makes a modification, the signal is sent from the interface to the cloud, and then from the cloud to the sensors and devices. The product is a very responsive and instinctive piece of hardware that significantly improves automation.
