Let Lutron's Maestro Occupancy sensor switch turn the lights or fan On/Off for you. Install a Maestro sensor and lights/fan turn on when you enter the room and then turn off automatically after you leave. This sensor features XCT Sensing technology which detects minor motion, such as typing at a desk or reading, ensuring sensor does not turn off inadvertently. Equipped with ambient light detection, you can customize your sensor to detect daylight so lights don't turn on with enough natural light in your room. Keeping the sleek design of the Maestro family, Lutron sensors will match the decor of any room in your home. Install a sensor in your bedroom so lights aren't left on mistakenly or in the bathroom for your exhaust fan. This Maestro Sensor works with any bulb type, including CFLs and LEDs or fans up to 3 amps. This switch can also be easily programmed to function as a vacancy (manual-on) sensor.
