What is Automation ?

Automation is any process that is self-driven and reduces, then eventually eliminates, the need for human intervention.

Automation was once confined to the manufacturing industry. Highly repetitive tasks such as automobile assembly were turned over to machines and the modern assembly line was born. Machines are excellent at repeating the same task without fatigue and without the errors that humans are prone to make in such jobs. This results in greater output, because machines can work 24 hours a day without breaks. Machines also provide a more uniform product. The IoT opens up a new world in which tasks previously requiring human intervention can become automated. As we have seen, the IoT allows the collection of vast amounts of data that can be quickly analyzed to provide information that can help guide an event or process. As we continue to embrace the benefits of the IoT, automation becomes increasingly important. Access to huge amounts of quickly processed sensor data started people thinking about how to apply the concepts of machine learning and automation to everyday tasks. Many routine tasks are being automated to improve their accuracy and efficiency. Automation is often tied to the field of robotics. Robots are used in dangerous conditions such as mining, firefighting, and cleaning up industrial accidents, reducing the risk to humans. They are also used in such tasks as automated assembly lines. We now see automation everywhere, from self-serve checkouts at stores and automatic building environmental controls, to autonomous cars and planes. How many automated systems do you encounter in a single day?

Accessing and Monitoring an IoT Network

The Home Gateway device acts as a local connection to your IoT smart devices. This device was designed to provide Internet access, wireless connectivity, and local logic for smart devices. The Home Gateway device provides an IoT registration service that is always turned on and an auto discovery service for Things in the local Ethernet and wireless network. After devices are connected to the home gateway, the user can control and monitor the smart devices from their smartphone, tablet, or PC.

Explore a Smart Home

Packet Tracer has a wide variety of sensors and smart devices that will allow you to design smart homes, smart cities, smart factories, and smart power grids.

To locate the available sensors and smart devices, select End Devices from the Device Selection box at the lower left-hand side of the screen. Next, select the subcategory Home. In this subcategory, you will see many IoT devices including an air conditioner, ceiling fan, coffee maker, and CO detector. These devices can be connected to your network wirelessly or with a physical cable.

To connect the devices to your network, you need a home gateway or registration server. To find a home gateway, select Network Devices from the Device Selection box and then select Wireless Devices from the subcategories.

To control the devices, you have two options:

1. You can interact directly with a device. Hold down the Alt key and at the same time click on the device to turn it on or off.

2. You can connect remotely over the network. Using a remote PC, tablet or smart phone, use a web browser to connect to the home gateway or registration server. From here, you can turn the devices on or off using the features of the home gateway or registration server.

To configure devices, click on the device to open it. After it is opened, multiple tabs are displayed:

• Specifications – describes the features, usage, local and remote control of the device

• Physical – available modules and power connections

• Config – shows display name, serial number, network configuration, and IoT server

• Attributes – displays the device attributes such as MTBF, power consumption, and cost

To configure the home gateway, click on the device. Within the device multiple tabs are displayed:

• Physical – available modules, and power

• Config – shows display name, interfaces (Internet, LAN, and wireless) to be configured

• GUI – shows services to be turned on/off

• Attributes – shows features and values related to device such as mean time between failure (MTBF), cost, power sources, and wattage
