Automation is the technology automate anything is performed with minimal human assistance. Automation or automatic control is the use of various control systems for operating equipment such as machinery. Automation covers applications ranging from a household thermostat controlling a boiler, to a large industrial control system with ten of thousands of input measurements and output control signals. In control complexity, it can range from simple on-off control to multi-variable high-level algorithms. The benefit of automation includes labor savings, savings in electricity costs, savings in material costs, and improvements to quality, accuracy, and precision.
