Abstract
Wireless sensor devices and IoT (internet of things) devices are two interconnected technologies that have revolutionised the way we interact with our surroundings. These devices are at the forefront of the digital transformation and are instrumental in creating smart and connected environments. This chapter first discussed the basics of wireless sensor devices and IoT devices, with pros and cons. Second, it discussed the major differences between the two; third, the major real-time applications of both types of devices are discussed, and fourth, the discussion about the use of AI and ML algorithms in these devices with detailed explanations of major algorithms are presented. Finally, there is a discussion about the future scope of both wireless sensor devices and IoT devices with AI and ML. Through this chapter, one can learn about different kinds of devices for different applications with various AI and ML algorithms. The future smart world requires many more smart devices for various applications. This chapter can provide a clear understanding of various devices and applications for the future smart world.
