Wattstopper CI-305 Occupancy Sensor

this product turned my lights on and off based on occupancy. I was able to configure it to turn lighting on, and hold it on as long as the sensor detects people in the room. I liked that when i leave the room the lights were switched off. A "walk-through" mode can turn lights off after only 3 minutes, if no activity is detected after 30 seconds of an occupancy detection. The price of the product was very attractive since on my locals stores they usually runs around $90-100 dollars depending on the store location.
