Let’s begin with the basics. IoT is not a new word anymore, it is well known as the ‘Internet of Things’. IoT generally refers to any devices / things connected via internet that generates data for intelligence, generally known as Smart Things. The collection of field sensors, connected devices, communication channel, data aggregator and analyzer or intelligence are considered as an IoT System. The primary goal of IoT technology is to sense, connect, collect, analyze and interpret data. ‘Data’ refers to information about various parameters collected that otherwise cannot be acquired manually. Simple example – Smart watches that read heart rates / pulse rates; Home appliances’ that operate on voice commands over internet connectivity etc.
