What is the Internet of Things?
According to Wikipedia, IoT is a network of physical objects or things embedded with electronics, software, sensors, and connectivity. These things interoperate within the existing Internet infrastructure. They achieve greater value and service by exchanging data with the manufacturer, operator, and/or connected devices.
Properties of things involved in IoT:
They are physical objects with input (sensors) and/or output (actuators). They interact with the physical world.
They have connectivity to the Internet or local connectivity via Ethernet, Bluetooth, GSM, Wi-Fi, or any RF transreceiver.
They exchange data with Internet websites or cloud or other things. Often this data is available to the end-user via smartphone, tablet, or PC.
They have some kind of unique ID like IP address, RFID, or QR code.
They do have small software logic that they follow. Once set up, almost no physical human interaction is involved.
