Smart building sensors are capable of collecting environmental and operational data of buildings and reacting to the collected information in real-time. Sensors capture data from preferred environments and transform their physical properties into measurable electrical signals. The components of a smart building must include a building management system for real-time control, utility functions, energy efficiency/energy management, security and life safety systems, and internet integration. It is more productive with lighting, thermal comfort, air quality, physical security, sanitation, and more at lower costs and environmental impact.
