Lutron Maestro MS-OPS2H-WH-C Occupancy Sensor Switch, Single-Pole, White

The Lutron Maestro occupancy sensor switch combines a wall switch with a passive infrared sensor that turns lights on when someone enters and off when the room is empty. Lutron XCT technology detects fine motion, such as desk work, so lights stay on while the room is in use. It can be set to automatic-on or manual-on (vacancy) operation, with adjustable timeout and sensitivity, and ambient light detection that keeps lights off when the room is already bright. Works with most lighting load types. This is the Canadian clamshell-packaged version.
