When something is connected to the internet that means that it can send information or receive information, or both. All it has to do is connect to super storage or to a super computer. The Internet of Things (IoT) promises to bring immense value to every organization. By continuing to connect all our things, people, and environments, we can unlock tremendous organizational value and achieve feats that will truly seem like magic. Most sensors and actuators today are already equipped with microprocessors, which can be used for parameterization, storing data, and controlling indication. To overcome the bottleneck of interfacing, and make additional functions centrally accessible for the automation system, IOT was introduced.IO-Link is based on a point-to-point connection between the sensor/actuator and an interface module. Sensors could be temperature sensors, motion sensors, moisture sensors, air quality sensors, light sensors
