Home automation system makes the operations of various home appliances more convenient and saves energy. With the energy saving concept, home automation or building automation makes life very simple nowadays. It involves automatic controlling of all electrical or electronic devices in homes or even remotely through wireless communications. Centralized control of lighting equipments, air conditioning and heating, audio/video systems, security systems, kitchen appliances and all other equipments used in home systems is possible with this system. This system is mainly implemented by sensors, controlling devices and actuators as shown in the figure. The sensors detects light, motion, temperature and other sensing elements, and then send that data to the main controlling devices. These sensors can be thermocouples or thermistors, photo detectors, level sensors, pressure sensors, current transformers, IR sensors, etc., which need an additional signal conditioning equipment to communicate with the main controller.
Industrial automation is the use of various control devices like PC’s/PLC’s/DCS, used to have control on various operations of an industry without significant intervention from humans and to provide automatic control performance. In industries, control strategies use a set of technologies which are implemented to get the desired performance or output, making the automation system most essential for industries. Industrial automation involves usage of advanced control strategies like cascade controls, modern control hardware devices as PLC’s,sensors and other instruments for sensing the control variables, signal conditioning equipments to connect the signals to the control devices, drives and other significant final control devices, standalone computing systems, communication systems, alarming and HMI (Human Machine Interface) system
Robotic process automation (RPA) is the application of technology that allows employees in a company to configure computer software or a “robot” to capture and interpret existing applications for processing a transaction, manipulating data, triggering responses and communicating with other digital systems.
