Building automation system (BAS) integrators combine the inputs of sensors, controls, and actuators to create a network of electronic devices that regulate various aspects of a facility's environment. Sensors determine a building's current status and forwards this information to a PLC which abides by commands from the operator interface. Controllable aspects through a BAS includes HVAC, lighting, power supply, and security capabilities. BASs are becoming more commonplace as a means of incorporating energy and labor efficiency into modern building design. Systems can often be controlled remotely from a centralized station or even a smartphone; such systems are becoming scaled to accommodate personal residences, aside from their traditional use in businesses, factories, and institutions.
