A device available from a major home improvement retailer, these items detect motion and automatically control lighting or other electrical systems. They are typically installed to conserve energy by switching lights off when a space is unoccupied, and turning them on upon detecting movement. For example, a homeowner might install one in a garage to automatically illuminate the space upon entry and extinguish the lights after a period of inactivity.
The use of such technology provides several advantages, including reduced electricity consumption, lowered utility bills, and extended lifespan for light bulbs. Historically, these devices have been employed in commercial settings, such as offices and warehouses, but their increasing affordability and ease of installation have made them popular for residential use. This growing adoption reflects a wider trend toward energy efficiency and smart home automation.
