INTERNET OF THINGS: SMART SENSORS, SMART APPLICATIONS AND SUPPORTIVE TECHNOLOGIES FOR AUTOMATION

Abstract

Internet of Things (IoT) refers to the linking of computing devicesalso known as nodes for communicationthroughwireless sensor networks.It automating the world processes with billions of sensors and actuators. IoT is evolving with each passing day.Sensors are used as a node for sensing and collecting data. A sensor is an electronic componentthat detects and responds to some type of input from the physical environment.Sensors are used to detect motion, pressure, temperature, moisture, sensitivity and many other physical quantities. The journey from smart applications to smart world is possible due to smart sensors. In thispaper,we have precisely reviewed the sensors with their specifications and uses in smart  applications. A wide range of smart applications are discussed along the sensors that bring the applications in working. Furthermore, an internet of things taxonomy has been created in context of sensors to smart applications. We also elaborated the IoT enabling technologies like wireless sensor networks, data analytics, cloud computing etc for better understanding of researchers.
